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 tether is stop, then we can be sure of Bitcoin going high, but if not, that means Bitcoin reaching $100k is in utopia.
Because as i am writing this tether as still planning to mint more of their shit token out of thin air to disrupt Bitcoin and other altcoin price.

They're the reason why other coin is not moving up, because all other coin are being pairs with tether in the trading market, not Bitcoin as it used to be.

So something must be done to stop this shitcoin the are created out of thin air, if you want your darling Bitcoin/Altcoin to reach the moon.
