The current alt boom is coming to an end and bitcoin will rule supreme once again!
Against all odds, when everyone proclaimed the "imminent" death of bitcoin, It has gradually emerged from a massive loss of dominance that led it from having 90% to only retain 30% marketcap in a few weeks, up to the current 44%.
It is true that the times of overwhelming dominance will hardly return before the emergence of many new altcoins with great growth potential, but the current recovery is a sign that whenever there is uncertainty in the market, bitcoin will remain as the preferred safe haven of all investors.
The market dominance of bitcoin is not really that important what it's important is its market cap and the reason for that is very simple the dominance of bitcoin needs to go down for the simple reason that every single day there are new projects emerging, and while many of those are not worth your time, there are always some good projects, some of them are going to get huge investments and that reduces the market dominance of bitcoin.
