I see this scenario to happen before next larger move of BTC up:
BTC will slide down for like 5-10%, ALTS will go down double that amount at least, BTC will gain again even larger dominance and after that it will go again even more.
Your thoughts on that?
It is very likely to happen, since bitcoin also has not undergone a correction even after these last movements have occurred, and the case of the altcoins if it is normal, because when the bitcoin rises, the altcoins go down and in the same way if the bitcoin lowers the altcoins go down, the only way that is considered that the altcoins follow a movements bullish trend is when the bitcoin take their bullish trend road, because my bitcoin go up, the altcoins go down in price because people sell altcoins and they buy bitcoins to not lose the movement, and once the bitcoin goes down in price or suffers a correction, the altcoins will go down even more and it is the ideal move to buy altcoins so that when bitcoin takes back its bullish career the altcoins follow it and generate benefits from a x2, x5 and up to an x10 of the same altcoin. This scenario is likely to happen, as you claim.
Of course all this is invalidated if the bitcoin makes a correction and comes back to $ 5K because if you do something like that it is because you will find offer at those price levels.
