I have been actively watching BTC Heat and can confirm, that although their algorithm is intended to give people the joy of "winning" some bitcoin, they do a rather fantastic job of preventing you from being able to do so.
I have followed all their rules, disabled ad blocking, and mined for additional spins, and have even played the "invest" game.
I have kept track of how many rolls I have made, and how many times I have "won" and logged them, the following information is the results.
| % to Withdraw | Rolls | Wins | Win % |
| 80 | 395 | 10 | 2.53 |
| 81 | 1052 | 10 | 0.95 |
| 82 | 510 | 10 | 1.96 |
| 83 | 576 | 10 | 1.74 |
| 84 | 1103 | 10 | 0.91 |
| 85 | 1471 | 10 | 0.68 |
| 86 | 1101 | 10 | 0.91 |
| 87 | 866 | 10 | 1.15 |
| 88 | 1186 | 10 | 0.84 |
| 89 | 722 | 10 | 1.39 |
| 90 | 986 | 10 | 1.01 |
| 91 | 2702 | 1 | 0.04 |
Based on the last record alone, for the 91% bracket, I have received 1 win out of nearly 2.5k spins, and see a dramatic drop in "win" rate thereafter. If anything, this looks like its an asymptote algorithm, meaning it will never reach the 0.035 payout. I have spent a couple of weeks doing this to provide this data to everyone here. Hope this helps everyone stay away from this place.
Not to mention, 95% or more of their ads are phishing sites.
Update 1 - Updated the last record (as I have now run over 2700 spins at 91/100% to withdraw)
