BTC dropping? I always say what goes up too quickly will drop just as fast.
BTC is not stable at all from the chart on the last 30 days. From $2800 to $1850 low today? Poor guy too anyone who had 100 BTC. Just lost $100k in the last 30 days.

The issue here is that while BTC is independent of all other alts, the alts are not independent of BTC and thats why the pump and dump happening for alt is not in anyway affecting BTC but the reverse is the case when it comes to BTC and just again to solidify the dominance of bitcoin in the crypto world that no matter how they try btc will still be leading while others follow.
