Hi all, i'm new to trading and i made my first wallet of bitcoin in CoinBase...now i would like to buy some altcoin but if i would like to transfer bitcoin to exchange like bittrex or other they ask me an high fee for tranfer like 12$ for transfer 100$ of BTC....is it possible? How can you make good trading if everytime you have to transfer money from wallet you have to pay so high fee? I did mistake something? thanks
You can try to deposit other coin like ether or litecoin then convert it to btc when you already sent it to exchange . that's the best thing to do if you want to pay lower fees than BTC fees.
That is exactly what i do. I also do the same when I am purchasing coins from fiat. As it just works out with more bang for your buck!
