What Altcoin with a current low Market cap do you think will explode in price this year? When I say explode, I mean 100X-1000X-10000X returns.
I think Siacoin (SC) will give more profits in the coming years but if your are expecting very much profits the you need big amount of investments don't expect one coin will give this much of profits.Invest on XRP,IOTA and SC these coins may explode in the coming years.
But there is no guarantee in the crypto currency profits some coins may bump and some coin may dump and some coin will fadeaway on long term so invest the amount that you can afford to lose.
