I will definitely like to trade but in small amounts.
The transaction fees at popular exchanges puts me off
Bittfinex: ~15%
Polniex:~25%
Kraken:~20%
How do you then make profit when you are only trading small amounts?
If the transaction fees eat you more than 15%, your trading amounts are really very small.
You probably should only withdraw after you do multiple trades and accumulate enough BTC.
