The fundamentals have not improved, and ETFs and MicroStrategy are not the fundamental reasons for this round of Bitcoin's rise; it is essentially about manipulation. Therefore, Bitcoin will definitely drop, just like it has in countless times before, and at that time, altcoins will only drop even more, with most likely being delisted. The frightening thing is that Bitcoin has not really started to drop yet, while altcoins are nearly gone. Cryptocurrency has already ended; no belief can stop the tide of history.
