Cryptocurrencies slowed down after strong rally into wave 3 of an ongoing five-wave bullish impulse, so current sideways consolidation should be just a correction in wave 4.
BTC dominance is actually still here and Bitcoin can be already progressing wave 5, but that's why ALTcoins are currently slower than BTC.
However, looking at the TOTAL2 Crypto market cap, which excludes Bitcoin, it looks like nice and clean bullish triangle pattern in wave 4 that can be coming to an end with final subwave (E).
So, soon be aware of a bullish resumption within higher degree wave 5 of III, which can push BTC and ALTcoin friends even higher.
