Hello, I have just found app Cobo wallet and they offer up to 11% ROI if you store and stake your Bitcoins here, also you can store many other alts here (Ethereum 2% ROI for example).
But I do not understand how you can stake non-POS coin. Who will give you free money? Is that safe?
Not only Cobo wallet offers it, there are more same wallets.
What is your opinion?
What does this staking benefits the crypto holder? Sorry, but it was just the first time I heard about it. I just mainly store cryptos on my wallets but not knowing about staking or in any sense.
