Yes, it's very cool, because all the altcoyins have gone up, everything is becoming more expensive. But maybe all of us are waiting for sevit in the near future. Maybe it's just decided to move it. So do not relax. Buy altcoyins, while they are still at a low start, then it may be too late. 
Altcoins are going up just because in the last few days they were going down. Since in the last weeks many people sold altcoins and bought Bitcoin, because they thought they would have been rewarded with B2X coins, basically for free. Since thhard fork won't happen anymore, many people started to buy altcoins again...that's it.
