Are you serious, man? Why would you risk your funds just to get some interest on them? As another member already said, Betfury also provides interest on staking, but not the same way Freebitco.in provides. Betfury has some wagering requirements if you want high-stakes rewards. But it is not really worth risking your funds just for a few percentage.
I suggest you withdraw the funds from Freebitco as soon as possible because they do not care about your funds anymore. If you ever face any issues, you won't get any support from them.
Yeah everything looks like it's pointing to a disaster. I've "survived" Celsius, FTX and many other "exits" so far, and it all smells like the same shit.
Use the website at your own risk, but don't come crying if you get your ass handed to you
