I have already Purchased ETH,NXT,XRP,START. When BTC starts to go down and down, what happened to those coins ?
The choice is made and even invested. Do not regret it. It was your choice and it deserves respect. Now about the main thing. The strategy of holding coins is the most profitable strategy that can only exist for altcoyins. I will say from experience, even the most ardent speculators who "burn coins in their hands" refuse fast money and go on long. Tip, the longer you hold the coins the more you will profit. And do not forget that we live in the golden age of the crypto currency.
Successes!)
