Everyone says that CMC dominance is irrelevant since it also includes stablecoins.
Yet, whatever params you use, there has been a sharp decline in btc dominance from the end of December 2020 (72%) to now (40%).

IMHO, this has to reverse within a week or two, otherwise it would be difficult to recover and we would move (regrettably for me) from one hegemon (bitcoin) to a multi-polar crypto world.
It is not a popular possibility around here and my largely btc position would affect my worth (or the lack of it), but someone needs to point out that this scenario is possible.

TLDR; a bear market starting in 1-2 wk to smash alts or a true multi-polar crypto world is coming. Btc ETF approval could swing the balance back in btc favor, but I don't see anything else doing it.
