I have a friend who is also staking, he bought ICP for 50$ in 2021, and he is staking at binance. But you can check ICP's current price, I don't think it can increase in price to help him recover his investment, let alone profit.
Unfortunately, this is the nature of high-risk investments such as cryptocurrencies. Your friend just hopes that IPC will ever reach the initial price again.
If this is the case, his staking investment has more than paid off, as IPC is still paying out very high percentages of coins through staking.
Basically, you should never be blinded by high APYs, they have a reason. Often the reason is quite banal, that the coin is highly inflationary ...
