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?
Don't lose your money by getting attracted to this no one is going to give you free money for having your money and your own wallet.There are lot of cases similar cases were there in history now the new one so just ignore it and go away for a legit wallet
