yes you are right the price of bitcoin suddenly experienced a price increase and in my opinion this is due to the influence of the USDT rumors so that there are some popes who panic and secure their assets by buying bitcoin.
I do not understand how this situation, which I read in the news, could affect the Bitcoin exchange rate?
The sharp rise in the value of digital money occurred at the same time as the value of the tether token, which is tied to the us dollar, fell to record low values — $0.92. Last time it was the same low in April 2017.
The cost of altcoin decreased after the major exchange Cucoin announced the suspension of deposits and withdrawal of USDT due to maintenance of the system. At the moment, they are available again, and the price of the cryptocurrency is gradually returning to its previous values, now it is $0.96.
In the process, Bitcoin is now declining back.
