So, i'm just starting out and I got Xapo in order to collect some satoshi to play around with. I was wondering if Xapo is safe to use? It lets me instantly transfer money from faucets to my wallet so I don't have to "collect X amount before cashing out". I've heard that online wallets can be insecure, should I get a safer (desktop?) wallet and transfer what I collect there, or will I be fine using Xapo? Thanks!
