Why? Until Tether (USDT) is stop from minting their shitcoin out of thin air then I think this will never happen.
You can check how many USDT that tether has mint this year alone, from January till now, then you will understand they are the reason why Bitcoin couldn't sustain the ATH of $60k.
When bitcoin was struggling to make $1000 several years ago people said something to say it would never reach $10000 when it got there and maybe a new all time high of 20000 dollars, a new bench mark was brought up saying bitcoin can't reach $50000 because coins being minted by some coins but it got to $50k and maybe a new all time high above $60k. Would we still be saying bitcoins momentum is over , I don't think so " that limited supply of bitcoin is the main key to its growth not some unrelated altcoin like tether.
