How OP ended up with that speculation if the crypto market starts to have no decent movement for this month, its the end. You are thinking the typically panic seller does, the crypto market is here to stay and it won't be as easy as you are thinking for its downfall. Just look on its market cap and where you can see it now more than $233B only. Digital assets that has this market cap is no joke.
The market value of encrypted currencies is not large. As long as prices continue to fall, it will still decrease. Most of the time, only the price of bitcoin can truly reflect the real assets of the market.
Continuous fall can lead to two results. It's either that falling scenario will continue or it will open up a new gateway for an increase.
I can't disagree with what you said that the price of bitcoin has truly affecting the crypto market, every altcoins. Once we see significant increase for bitcoin, alts are also increasing but there are cases where its different. Bitcoin price increases, alts are going down and I don't know what's behind it but it only happens when bitcoin dominance increases.
