isn't it if the bitcoin trend continues then the altcoins will also experience an increase in price! I think there is no problem with altcoins and now it's slow in rising prices maybe still afraid that bitcoin will suddenly dump
Thats what usually happening, if bitcoin price increase alts are following but this time it seems bitcoin alone is getting the limelight.
Well there's no need for you to sell your alts just because of this thinking that they might get dump. Alts has their own season on when to soar high, thus just wait for it because sooner or later it will chanhe movement. As long as the altcoins that you hold are well-established then most likely it will increase in time.
Alts will follow the trend but remember, it depends on the alt itself. If your holding a strong alt with strong foundation and continuous development, then you have the chance that it will really increase as well. But if you have a crap alt, with no progress going on, team is missing in action, guess you know the answer where your alt is heading to. So this question relies on what alt you are holding. It doesn't depend on bitcoin alone.
