Here's how I calculated initially, which is very rough back of the envelope math, and when the price was about 100 sats/FUN:
I looked at WOF spins primarily, as that's what I see as the biggest perk of the program. The extra interest doesn't amount to much by comparison. Here's what I calculated:
At 5000 Fun tokens, the cost is currently 500k sats. After a month you get 3 extra WOF spins and it scales up to 6 daily WOF spins after a year. For the sake of simplicity, I'm just going to calculate 6 extra WOF spins from the start. WOF spins are generally worth 50 sats. Either you get 50 sats or 50 rp which given enough time you can convert to 50 sats if you make it to 100k rp. Sometimes you get more sats on a spin, but sometimes you get lottery tickets too which in all likelihood translate to 0. So expecting 50 sats per spin is reasonable and I would say necessary when you're calculating time to recover investment.
At 6 extra spins a day, you're looking at 300 sats as the extra perk. On a 500k sat investment cost, that's 1667 days, or 4.56 years. And that's only if FUN holds the value you bought it at. Taken that as a given, it's not a compelling investment given the risks. I think you can get more perks at much higher investment costs, but honestly, that's even more risky in my view, so I calculated on what seemed like a reasonable test tier.
Now the price has fallen and the time to recoup investment has fallen with it, so it's gotten more attractive. But I haven't accounted for lost interest income necessary for converting to FUN, and I'm also not assuming any gains on FUN holdings (which is folly to take as a given). I'll continue to watch the price of FUN and if it continues to fall, I'll be more interested, but you're still at a 2.7 year recovery period (VERY ROUGHLY) for a 5k FUN tier investment, and that's an awfully long time to break even and take on the unknown risks of holding a low-utility alt.
Your calculations only apply to a pure claimer but not to a regular player. You didn't include the rakeback in your calculations, neither the amount of additional earning interests you can get.
Yeah, since gambling is a net loss statistically, you wouldn't include that in a break even calculation. If you're a regular gambler on the site, you are likely to have more tangible benefits under the program
compared to where you would be without it. However, since the marketing around FUN are geared towards an "investment" I calculated breakeven for investors.
And the amount of extra earned interest is pretty small compared to the opportunity cost of buying FUN up front. If you max out the FUN tier, you get an extra 25% of the interest rate
after 1 year, so instead of earning 4.08% you're getting 5.10%. The extra 1.02% is the interest benefit, again
after 1 year. It currently costs .325 btc to get that bonus (at the current 65 sats/FUN), and there's 1 month lag time before you start accruing any benefits, so it takes 13 months total before you'll be getting an extra 1.02% on your onsite balance. In the meantime, you've given up 13 months of daily compounded interest on the .325 btc which comes out to (roughly) .01326 btc (might actually be more, I did a simple 4.08% calc, but can't remember if that already factors in the daily compounding or not). You have to have a significant amount of additional btc onsite earning interest in order for the extra interest to pay back the lost interest income from holding FUN, in fact more than 1.3 btc for you to eventually earn back the interest you've lost with extra interest.
Examples of interest lost and gained at 2 and 3 btc onsite:
Years Int. Lost Interest Gained on 2 btc Interest Gained on 3 btc
1.083 .0143 (Some) (Some)
2.083 .0276 .0221 + some .0331 + some
3.083 .0409 .0424 + some .0637 + some
4.083 .0541 .0629 + some .0943 + some
You earn some extra interest in the first year, but I don't feel like doing the calculations with the scaling rates because I'm trying to keep this simple and just ballpark it. Safe to say that at 2 btc onsite earning interest, the interest pays itself back sometime between year 2 and 3. At 3 btc onsite, you earn it back before the second year is complete. I don't keep nearly that much on the site... not your keys, not your coins and all that, but if you've got significant btc onsite (more than a couple btc), you'll get a lot more benefit out of this program, assuming it's not changed. (Remember, holding 2 btc onsite is about $100k at this point. That's a good chunk to have somewhere with no safety net. Stocks and bank accounts are federally guaranteed at that amount if the operator fails.)
Another thing to consider, since this is going to add costs to the operating expenses of the site, this program has to significantly boost gambling income for this program to remain unchanged because it generates a profit for the site, which is another risk factor you have to consider. Even with a good reputation, I'm not likely to put a significant amount of btc in some else's hands and trust it to be safe, but I'm probably far more cautious than a lot of people here, so take that for what it's worth.
