coinbase is a really nice wallet that everyone loves.
I saw a friend of mine, downloaded it and signed up, then he sent a small amount from somewhere and never cut.
I recommend a wallet that I love to everyone.
If you do buy and sell this app will hardly mess you up, but you can use it in a really handy way to use it once in a while. I am constantly using coinbase for coin exchanges.
It is a high volume wallet and has deals with some new coins. Trying to increase the number of users by making new new airdrops is a really good tactic.
