Slightly off-topic, but this kind of thread reminds me that there currently isn't any sort of software that allows you to easily track gambling investment.
I mean, you have all these crypto portfolio apps, literally dozens of them, but not a single app to track investments on crypto casinos.
Excel is great, but it takes quite a lot of time to manually create and fill in the sheet.
Really? I'm a developer myself and could create such an app, but it's not something that I would do for free as a hobby project, because getting the precise stats of casino investments is just a slight curiosity for me (even though I'm investing in casinos for a long time, and plan to keep doing so).
Well, it also depends on the price the bitcoin was during the time of your investment. You should take that into account if you calculate values in Dollars or Euros instead of plain BTC. The price volatility will make a huge difference in your ROI. Other calculations are quite straightforward. If you want me to help you doing that, I can do it for a very small service charge and also show you formulas in excel so you don't have to pay anyone next time.
I'm only interested in gains from casino, not from price changes (I also invest in alt bankrolls), that would be an unnecessary complication. Thanks for your offer, but I'm just looking for a general advice.
