Upon my analysis, the investors and whales do not want to rush with the altcoins bull run , but rather want to study how stable will be for bitcoin.
Your analysis can be correct but seen from the trend it looks like the altcoin will not be bull run easily, surely the price of bitcoin will change again because the price of falling bitcoin prices is just like a reasonable correction done by traders who take profits.
And as the last 24 hours showed, Bitcoin is as unstable as ever, but that's why we love it so much and why speculators just can't stop having enough of it. The warning signs were there though, altcoins were losing crazy ground the entire day while BTC was pumping, so you know people for sure were selling off alts into BTC, and then, when they stopped and sold BTC for fiat, everything collapsed.
Short term though and that's what happens when things go up so fast. It'll be fine.
