Some help. So just using a smartphone what are the best apps to store bitcoins in taking I to consideration transfer fees and ease of transfer. Right now I use coinbase as a buying platform and Bitcoin wallet as my wallet but it's a pain to transfer and not sure about the safety of the Bitcoin wallet.
Well, it really depends what you want more of, convenience or safety, since your using a mobile, I would think that you value convenience over safety. I would recommend using mobile wallets such as coinjar touch, electrum wallet or green address. I am currently using electrum wallet for desktop and would totally recommend using it for mobile and desktop, everything is in a very simple fashion, and I have checked out the mobile app and it is also very well made, would totally use it, except for the fact I do all my bitcoin transactions on my computer and never use bitcoin in the real world. Enjoy!
PS: I would also recommend getting a trezor or ledgerwallet or any other hardware wallet to store the bulk of your bitcoin.
