from that incident I began to believe that maybe this was a bull market sign,
but what happened today is the market is not green, but red.
how do you comment about that?
That was no way bull run but a way to secure the peoples money. I mean most of them used to rely over the USDT so that they can prevent their investments from going down. But when the news about the delisting came then it was like panic situation everywhere, leading peoples mindset to all new level where they thought they can now loose their money in the market. So now BTC was thought to be more and more secure place. Once the trading started against the BTC then it pumped naturally and thus caused the price rise.
Now it is good thing because people may not choose USDT due to its insecurities. Either they will keep it in BTC or may put it in ETH and pump it as well. Just like the old days.
so in your opinion this is a natural and frequent thing on cryptocurrency, where the popes take people's money when they are hit by panic when they hear about delisting USDT
