The Math Behind the LindeX

LindeX MathThe recent instability in the LindeX Exchange has caused a lot of people to begin questioning the reasons … and the solutions. But to really understand what is happening and why, first we must understand the Math behind the LindeX. Even though I’m not a trained economist, I do know math. Today’s post will hopefully explain things using math but in a basic manner that doesn’t require a sheepskin and a super-computer to comprehend.

LindeX Basics

The LindeX is a basic “Money Exchange”. That means it lets people exchange one type of money for another. The LindeX specializes in exchanging Linden Dollars for US Dollars. Just like many real-world exchanges, the rate of exchange is subject to many varied influences. Unlike real-world exchanges there is no regulatory agency or body of laws that oversee its operation. In other words, it can go nuts as a result of panic and misinformation, but there is no controlling agency to keep it from going too crazy.

From Investopedia:

The money that is traded on LindeX is constantly monitored and evaluated by Linden Lab to generate economic statistics of the virtual world. LindeX is essentially an exchange where users called residents can trade and exchange Linden dollars with other residents; users do not trade directly with Linden Lab. (underscore mine)

Buying and Selling on the LindeX

When you “Buy” on the LindeX, you are using real-world US Dollars to purchase some number of Linden Dollars. When you “Sell” on the LindeX, you are converting Linden Dollars into US Dollars. According to Linden Lab, the LindeX is a “User to User Exchange”. That means they are neither Seller nor Buyer; they are only the entity that runs the machinery.

The LindeX Buy / Sell Gap

There is always a difference (or “Gap”) between the best Sell Price and the best Buy Price. This Gap ensures that the LindeX cannot become a tool for fraud and illegal speculation. The Sell Price is always lower than the Buy Price. Thus anyone trying to “Buy low and sell high” … can’t. Even so, don’t let yourself believe this is done to protect people using the LindeX. The whole purpose behind the Gap is to protect Linden Lab from legal intervention and regulation. It gives the impression that the LindeX cannot be used for money laundering and thus keeps them off the government’s radar.

Basic LindeX Math – Fees and The Gap

The size of the Gap is usually around L$10 to L$15. With a center point of about L$266 per $1.00, the Buy and Sell prices are usually around $0.045 (4-1/2 cents) apart. That may not sound like much, but multiplied by an annual Sell and Cash Out volume of $60 Million, that’s a total Gap of $2.7 Million. That’s a pretty sizable amount.

Why does this matter? Remember that the LindeX is a “User to User” Exchange. That means that in order to stay in operation, the money out must equal the money in. Thus the two numbers must be roughly the same, only differing by the amount of the Gap. The Fees charged are based on the type of Transaction and the number of Transactions. A full list of applicable Fees is found at LindeX™ Exchange Fees.

(The Gap Value is calculated in US Dollars because that is the “Outside” currency. The “Central” currency is the Linden Dollar, and that’s the amount that must balance. The Gap Value is thus calculated by subtracting the US Dollars taken out from the US Dollars put in to purchase Linden Dollars.)

LindeX Income for Linden Lab – Fees and the Gap

So lets add them up. With $60 Million cashed out last year, the total Seller Fee at 3.5% is $2.1 Million. The Buyer Fee is harder to calculate because it is charged per transaction. But we can guesstimate that with $62.7 Million in L$ Buy orders and an average purchase of $100.00, there would be 627,000 times $0.40 per Buy Order for total Buyer Fees of about $250,000.00. The final totals then are: $2,700,000.00 (Gap) + $2,100,000.00 (Seller Fee) + $250,000.00 (Buyer Fee) or just over $5 Million.

The last set of fees that matter are the Transfer Fees. Just recently Linden Lab changed the fees for Cashing Out (Process Credit). They now range from a minimum of $3.00 to a maximum of $15.00 per transaction. Applying the law of averages, we can estimate the “Average Cash Out” at $600.00 (an average $9.00 fee at 1.5%). A total of $60 Million cashed out with an average transaction of $600.00 equates to 100,000 Process Credit transactions. At $9.00 each, that’s $900,000.00 in Process Credit Fees.

Caveat: I’m going to give the benefit of the doubt to Linden Lab on the Process Credit Fee. Most services like Linden Lab uses charge around 1.5% to 3.5%. Since Linden Lab is only charging 1.5% with a maximum limit imposed, I’m going to throw away the Process Credit Fee and not add it into the income equation we are building.

The Bottom Line for a Stable LindeX

Okay, let’s summarize and figure out just how much Linden Lab is earning from operation of the LindeX. As we calculated above, Every year they are taking in roughly $5 Million from the Gap and various Fees. Since they are paying out $60 Million to their customers every year, their total percentage of “The Take” is approximately 8.3%. That’s a pretty good chunk of change in anyone’s book. But apparently Linden Lab is not happy with this amount.

In a recent Lab Chat, Ebbe Linden commented that they are looking at various ways to increase their piece of the pie. Specifically he said:

…we’ve also taken some actions to pick-up some of the revenue elsewhere; on the exchange and on the redemption side of the equation to compensate a little bit…

An Unstable LindeX

As we’ve all seen, recently the LindeX has been anything BUT stable. Linden Dollars purchased to spend in Second Life are usually “held” for about a week before they are sold and cashed out again. If the LindeX Exchange Rate goes up, it has the most impact on Sell Orders. And this is where the math gets a little tricky, so hang on tight.

The average Sell Price was about L$252 per $1.00 US. Just recently it climbed to L$262 per $1.00 US. What that means is that at the lower rate, there must have been around 15.1 Billion Linden Dollars sold. ($60 Million × L$252 per $1.00) But at the higher Exchange Rate, that same 15.1 Billion Linden Dollars will only result in $57.7 Million. That’s another $2.3 Million into Linden Lab’s pocket.

Take from Column A and Add to Column B

And there’s the real bottom line. In a stable LindeX market, Linden Lab stood to make around $5 Million. But because the LindeX has gone wonky, they now are looking to take in an extra $2.3 Million, or a grand total of $7.3 Million. That’s pretty darn close to a 50% increase in projected income … just for “destabilizing” the LindeX. Of course that also means that Sellers will take out $2.3 Million less this year. With our projected 100,000 Process Credit transactions, that yields a total LOSS of about $23.00 per transaction. If the average Seller cashes out once per week, their total losses add up to just under $1200.00 per year.

The LindeX Roller-Coaster

LindeX - Declining Linden Dollar“Holy Smoke! What have they done to the LindeX?”

Over the past few weeks, the value of the Linden Dollar has plummeted. There are lots of reasons suggested for this precipitous change. Today we’ll discuss some of my favorite theories. And I promise, you won’t need your Tin Foil Hat .. much.

Before we start let’s review some LindeX™ basics.

Copyright Law and Second Life

It’s no big secret that there are literally thousands of items for sale in Second Life™ that violate Copyright Law. When Mesh was added to the platform, the sudden flood of copied and otherwise ill-gotten items virtually exploded. For their part, Linden Lab has tried to keep a lid on things, but the attitude of most people using Second Life seems to be one of “everyone else is doing it.” To say it makes LL’s job harder is a gross understatement.

Today’s post comes about as a result of an interesting conversation I had with a fellow SL Resident about their intentions and opinions on Copyright Law. It was a follow-up of sorts to a post they made on the SL Forums asking for someone to help them break the law .. and my response to their post.

I spoke before about the two very different platform models embodied by Facebook and WordPress. Today’s post will take the Facebook perspective, present theories of how a Virtual Reality platform could be built using that model, then finish up by discussing the possible outcomes. I call it “Project FaceSanBookSar.”

It’s important to note that this post is also one of my “conjecture” essays. That means I have no insider knowledge or information, I just have a lifetime’s worth of experience doing stuff like this. Okay, disclaimer out of the way … let’s begin.

The Bridge to Project Sansar

Linden Lab is breaking out of their walled garden by devoting their efforts toward a new product, currently code-named Project Sansar. As high-tech product development efforts go, this one has all the secrecy and mystery of a good CIA Plot or a bad spy novel. Either way, without knowing any particulars of the project itself, we can make some very solid evaluations of their efforts and their chances of success. Perhaps even so far as to estimate how big any success might be.

Scratchin’ My Head … Again

I just got a private message from a Moderator on the Second Life Forums. The message was to notify me that I had violated the Community Standards by using profanity in a post. Now what confuses me is that the Forums have an active “Profanity Filter” that converts all banned words into scrambled letters and asterisks. And I didn’t engage in “creative character games” to avoid said filter either. So what did I do that the filter allowed … but the Moderator didn’t?

Here’s the full message, including my original post, in screenshot format:

At any rate, here I am again … scratchin’ mah haid and wunnerin’ …

The Rewards of Customer Service

November 3, 2015 by · Comments Off on The Rewards of Customer Service
Filed under: DGP4SL Info, Linden Lab and Second Life, SL Marketplace, The Project to Save Second Life 

Customer Service is that ephemeral quality about a business that is tough to define in words, but crystal clear in experience. We know when we’ve been treated properly, our concerns or issues taken seriously, and our business appreciated. We also know when we’ve been discarded, disrespected and dismissed. It’s no secret that Good Customer Service is something every company should provide. But many choose not to, and their reasons range across the map. So I thought I’d perhaps convince a few of them to reconsider their decision based on my own recent experience.

This time that experience comes from the Seller / Merchant side of things, not from the usual “Customer Perspective”. Confused? Read on …

Filed under: DGP4SL Info, Linden Lab and Second Life, New Products, Technical Info 

The SL Viewer and its genetic children are the magic lens by which we “Live” in the Virtual World of Second Life. When it is doing wrong things, it sullies our enjoyment and makes it more of a chore than an enjoyable pastime. That’s why bugs like I discuss today are especially important to exterminate. Sadly the Executioner for this bug seems to be taking the slow boat approach. And I’ve run into it full speed ahead.
