Op, consider it carefully before taking part in such things. There's always a risk when you're staking your coins because it means that you're giving some other party the keys. Then comes the concern over it being worth it in terms of profit. How much will this staking give you annually? 5%, maybe 10% if it's a very good deal? Well, Bitcoin can go 10% up or down in a matter of days. So aren't you better off simply hodling your BTC independently because this change is quite insignificant compared to volatility? You can also try to follow cycles with these 10% increases and sell the excess for fiat or a stable coin on an exchange.
