Here I am using every service perfectly and at perfect timing because exchange to exchange option to have for the trading is a better option to make profit .
Here I am.in this field since 5 years and seeing that exchange to exchange have different different price of buying and selling , so why to not buy at one and sell at other , so from that day of such type of the understanding , I started to use every legit exchange .
Perosnally I am using zebpay , btcxindia , coinsecure , unocoin , locabitcoins.com for the buy and sell of the bitcoin .
And for the altcoins trading I also use every ( yobit , poloniex , cryptopia , livecoin , novaexchange , c-cex.io , bitrex )exchange Because same coin have different price , so better to sell at one site and instantly buy at another without any transaction is a better option to make reading fastly .
