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?
wow. this sound's like ponzy scheme with blockchain mask. I don't know if any stake system with non POS coin can give much ROI ?. so be aware brother, there's so many systematic way for gather people's coin.
