Not scam, but definitely shady as fk.
So about 2 months ago I made a mistake and sent a deposit to this site which was too low. The min deposit for ETH is 0.005 ETH and I sent 0.00391249 ETH . Well, my mistake, stupid me. Obviously I contacted support and they told me there is nothing they can do, blablabla.
As you can see here, nothing was credited:

The money though still went to my linked ETH address, where it remained for 10 days and had not been credited to my account.
Today, just for the fun of it, I checked this address again and what do you know, they transferred those 0.00391249 ETH to their hot wallet.
Overall I have had 2 deposits in ETH, the one that was too small and another one 10 days later, the same day the total amount (both deposits combined) were sent to the hot wallet, yet only the 2nd deposit of approx 78$ (0.0188 ETH) was credited in my account.
All transactions can be seen here:
https://etherscan.io/address/0x3c71286a5a33352b87b25219f4cf64f9010aac13So not only did they not credit it to my account (which as I said is my fault) they basically then took that money from my linked wallet address and made it their own.
I would understand if the ETH would have been stuck in the wallet forever, it is what it is. But sending it to their hot wallet and basically stealing it is worth sharing this in here.
This practice is utterly disgusting. Why there is this minimum amount anyway I never understand since every amount over the limit gets credited automatically after 1 confirmation. My feeling is they want to pray on players making mistakes like this and then profit from them. Deposits I have sent to wrong to stake still remained in the wallet to this day, for years now. Betfury only took 10 days to make it their own. Garbage site!
