I'm not surprised that Bitcoin has been able to surpass a new ATH again this year, which means Bitcoin has experienced twice ATH this year in different months with not so long duration, which is about 6 months(+ -), and this is lagging -again proving that Bitcoin continues to strengthen and is trusted by everyone,
In 2021, anything beyond $19,800 must be a new ATH and this way, we had multiple ATHes in first four months of this year and the current ATH is not second time we are seeing an ATH. Like you and many other people, I am also not surpriced on seeing the bounce back of bitcoin as it is a highly expected one.
what I'm surprised is that all the popular Altcoins in the market have not reached their new ATH after having reached it together with Bitcoin in the previous 6 months.
Most altcoins may not see another new ATH here after as they might get dumped too hard and then might get delisted from exchanges. If you calculate ATH in USD value then some coins may try to satisfy you for the money you wasted with them.
