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 billion billion 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 that are being created out of thin air, if you want your darling Bitcoin/Altcoin to reach the moon.
The price of bitcoin is not monetized with tether or even any fiat, we just calculate the price in terms of fiat for easy identification. By the way people can sell their tether and still the value of bitcoin is not going to fall so only tether investors are at risk and more decentralized stable coins are coming up which will put an end to this tether minting.
