Well, dumping once you already knee deep in the dump only ensures a guaranteed loss.
If you are confident about the long term prospects of an investment, then holding on for longer might just work. I won't be selling any of my Eth or PoS crypto currencies any time soon. It helps that crypto makes up less than 15% of my portfolio.
Not really, you can dump and buy lower. Dump and not buy back will guarantee losses. Usually you dump based on panic and not buy back that’s how wealth is lost usually. Most assets don’t go to zero after someone sells, they may go lower but will have a bounce point somewhere down the line.
