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.
I don't really see the connection between a high USDT supply and the price development of Bitcoin and also of the altcoins. I mean just because there are not so much trading pairs with BTC now anymore does not decrease it's value in my opinion and it also makes sense, that stablecoins like USDT are now used more for trading paris because then you instantly know the price of the coin that you want to buy and you don't have to convert the price to USD first. I also think that BTC is not anymore a currency for the daily use as it has just become to valuable now, it is more a asset to invest and hold for a longer time just as you do it with for example gold. Don't get me wrong, i don't like USDT either because we can not be sure if every USDT is still backed by a real USD but i just don't think that i has an impact on the price of the other coins including BTC.
