The entire crypto market is pegged to Bitcoin and price movements of altcoins have been known to respond to movements in the price of BTC. Two days ago, there was a sharp drop in the price of BTC and 98% of alts were affected, some are yet to recover from the shock. This implies that for any major crypto explosion to be triggered it will have to done by BTC
Exactly, it is as if people are obsessed it to try to make altcoins independent from bitcoin but that is only going to happen once the developers of those coins stop copying every single thing that bitcoin does, once that happens then altcoins will begin to move independently but since many are coins are just scams or have very low quality the chances of that happening are not very high.
