Please take look the chart below:
I just took NEO as a representative for an alternative coin or a new coin other than the established ones such as BTC or ETH. You can clearly see the following pattern of behavior: as BTC moves up, Altcoins move up faster and overtake BTC.
In a downtrend (such as the February/2018 BOTTOM), Altcoins move down faster and heftier. The gap is now being closed as we speak which I take as a BULLISH indicator for BTC which might indicate, the trough is behind us.
