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?
after reading your thread i definitely sure its some scam wallet who will just steal your crypto and i don't think it's a good idea to invest your money in this type of scams.
