Bitcoin Gold (BTGBTC) is showing some early signals on the 4h timeframe pointing to higher prices, which also means if there is follow-through that the correction is done.
After Bitcoin hits a new All-Time High, if the Altcoins start to climb this move can be really strong.
Many others are showing similar signals... Still early though.
But we know that when Bitcoin starts growing, it is only a matter of time before the Altcoins also grow.
