Which wallet does have low fee?
I really want to know this (the question) because I want to know where can I have my official wallet for good.
Which wallet do you prefer? and why?
which is the safest?
You can adjust the fee, for ethereum.
Myetherwallet only provides you ethereum wallet, not bitcoin wallet. Bittrex has ethereum, bitcoin and most of other leader altcoins.
In bittrex, you're not given the private keys, in mew, you're given.
