I don't understand you are selling Bitcoin and buying Bitcoin again.?? I don't have a good idea about this but if you want you can buy Bitcoin by selling your other currency Altcoin but I am not sure if it is true that you are going to sell Bitcoin and buy that Bitcoin again.

At present I always like investing in Bitcoin very much. Investing in Altcoin is very risky so I would suggest selling Altcoin and marrying Bitcoin.
