Good question!
   I saw some wallets that pays interest just for holding your crypto-currencies there. It sounds nice, but
I don't know how that works and can we trust this wallets with our money!?
   Freddy11 are you using this wallet, or you promoting this wallet? I would like to hear more about this,
I never tried anything similar before. It would be good for me to store my coins in same wallet and get
some interest on them, but if that means that I am risking all my coins for some interest I am not for that.
