It is note able that almost all altcoins are now 80%to 90% negative from their all time high due to this happen only bitcoin uncertainty.
Now this is not clear what happen to next on bitcoin near future because bitcions dominance is increasing and altcoin crasing.So becareful if you holding any atcons for long term investment ...
There are still who could come up and follow the market surely most of the alt-coin drops down,
But we have seen them rise up just like Bitcoin and they are also surviving so we couldn't tell for sure that it would be bad for a long term hold.
If I'm I will choose between altcoins I'll choose the top 100 altcoins because of the competition for titles. Prices of altcoins can possibly move when bitcoin hits a hard pump, Their value might go down and up as well.
