Everyone knows this. Do you suggestion on any online wallets and desktop wallets to save the XRP along with the bitcoins in the same wallet provider. I do not want the answer that hardware wallets are only the safest one.
I believe people having various coins in the online wallet those are attacked by the hackers but desktop wallet are not been hacked as of now. So is there any desktop one.
