The definition of the post is that: today it is more profitable to have bitcoin but in the immediate future it will be more profitable to have ethereum. These variations indicated by the eth / btc will be more volatile lately, it would also indicate that when one rises the other falls but even with more determination, clearly avoiding the general collapse of everything.
examples:
maybe ethereum 2000$ / btc 30000$
i think the aproximated price for ethereum right now is 1550$
if bitcoin reaches 50.000$ and ethereum drop to 1550 is a normal price. then we must check all because the move start close of these ranges
