I will never stop buying Bitcoin because I am a trader and will never stop trading because trading is a way of earning for me and I can't stop it .
But if the buyers get down and sell will increase and sell in huge then ofcourse I will stop buying whether whatever is the rate of the Bitcoin is in the market of cryptocurrency .
But here I am also thinking that and sometimes doubt that whether  I am making money in Bitcoin really , because the earning of 1-3$ per deals results into loss of 50% because of the increase in the fee , so I am thinking to buy altcoins like ETH , dash , dgb , ripple etxc , because these have very low charge for the transaction from one wallet to another .
So with the Bitcoin deals in control I would like to have buy of altcoins instead of the Bitcoin to USD only .
