The statement is made to stablish what I believe is obvious, but considering what I've been learning from all on CT, this is my opinion of course, not financial advice.
BTC market share around 10T Total Market Cap would reach maybe 3.3 on present cycle, where ETH may reach 1.1 with SOL.D above it by small % maybe reaching 14% on a very tiny window.
All behaviour of Altcoins Dominance regardas past cycles is suggestion the market share is going to expand (logic) and the race would be to hold above 10% and for BTC to hold AND sustain, above 25%.
I Believe BTC will touch the base of the Fib Channel, around 14% meanwhile the window closes and the market shuffle is over.
Happy Harvest.
