I see that btc almost hit 25k$ this morning and i believe that if btc rise 25k$ most of the altcoins will also rise or follow btc trend, so i think this time will be the very best time to decide what altcoins can give us profit in short term investment if you have any suggestions please extend or let me know.
Just be careful, sometimes it's not mean Bitcoin is pumping, altcoins are following also. Sometimes it is different from altcoins.
But I believe as long as Bitcoin will not dump, altcoins are safe. And what I also observed is, altcoins are following Bitcoin after Bitcoin pumped or Bitcoin became sideways only.
Imperials move wherever the kind does. So there is no doubt about that, but, I've also seen at times, some altcoins move in an opposite direction of Bitcoin's movement. If it's going up, those alts go down, and when it starts going down, those alts start pumping, but that only last temporarily and then they readjust and join others.
Also, altcoins are never safe, no matter how good of a performance Bitcoin is putting up on the market. Altcoins always carry huge risk as we have seen how they take no time in collapsing after building very large user bases, great trust and everything.
