There are many ways to trade your bitcoins. For you what is the best?
Well, I guess the better and good way I think is use our bitcoin in the exchange platform to buy some other altcoins which is a legit one then its up for the traders if they're gonna trade it for a short or long terms to get profit in the long run.

I am sorry in advance but I dont think so its sagacious to buy altcoins for bitcoins. Its good to do trading at famous exchanges with bitcoins but buying altcoins or any other coin is not a good move. Personally I feel that bitcoins are an epic asset. One should keep them for as much time as possible. When prices are high, and then convert them to fiat.
