That pretty much depends upon BTC price since you are paying price in satoshis (BTC decimal places).
Also, if you are dealing in say $1k worth of bitcoin $2-3 fees won't hurt much.
Alright, but should I place them in a wallet like exodus or should I place them in bittrex? I mean I'll be holding them for a pretty short time, like 3 or 4 months. Also, can you suggest a trusted and efficient btc or alt coin wallets for mobile? I was thinking of coinomi, something I can store alt coins at.
