How exactly do altcoins gain value? There are so many altcoins out there and honestly you can see connection among these in terms of the drop and rise of price.
Well some of altcoin's price are related to bitcoin because major funds of that said coin is also bitcoin and other major coins. So automatically when bitcoin is down so do they, however the difference is that if that coin has alot of investors then it will move upwards yet bitcoin will stay the same.
