I have been involved in the cryptocurrency market for over 2 years and I never thought this was a financial bubble because cryptocurrency is a very well developed market even when global economic decline. The efficiency and practical application help confirm the position of this market in the world. I believe that cryptocurrency will not stop here vad even further.
I can't say it's a bubble, but partly it reminds the bubble of dotcoms that happened in the beginning of 2000s.
I think this market will self-clean and many altcoins will die. This is normal and it happened to all markets. This market has been overheated and such a decline that we see sales is normal.
