This reminded me of my days in real estate investing. In 1990, I went to a real estate investments conference / meeting. And, at the end of the presentation, the speaker said: "No matter what you do, don't sell now!"
For the younger audience, the US economy experience inflation and mortgage interest rates has gone to over 18%! Then, the market crashed and home prices with it in 1982 - 1984. Home prices in Houston, Texas seem to have bottomed out in 1987 - 1988.
So, if you have not sold the virtual assets, AKA crypto-currencies, don't sell now!
