I gave BetGalaxy a try. Here are my impressions:
- Account creation process was simple enough.
- Deposit (using TRX) was smooth and fast.
- Withdrawals got delayed (already addressed by OP), but always completed within 8 hours.
- UI has minor bugs, but not going to spoil the experience.
- Games are extensive and connection to the third-party servers are quite stable.
- Profit-sharing model seems solid.
Now into the bigger points resolving their unique div pool system.
- The documentation is extremely minimal.
- The Dividend Rewards cannot be used to play, which is a bummer. If you collect 25 USDT over time from the div pool, while the avg. network cost to withdraw is also 25 USDT, you basically get nothing.
- For now, it also does not seem possible to withdraw the div rewards in multiple tokens unless you have deposited the said token. So if you deposited only TRX, then it is the only token that you can withdraw even though you get the div rewards in 10+ different tokens.
- Finally, it is a HUGE disappointment to know that after the mining got to Level 2 yesterday, the mining cost stays at $0.05, instead of increased to $0.1. It was even tweeted as if it was a good news. This means for the early players, the decay rate stays the same and the minted COSMO tokens will burn out much faster as well. More importantly, it indicates that the mint cost is set manually or the algorithm can be tempered. So at any point, the house can change the rules instead of following what they stated in the whitepaper.
Hopefully, OP can address my concerns.
We made this change to make it easier to credit!
