Talk about how to rescue yourself after being trapped by altcoins
If you timely switch your altcoins to BTC or BNB when they are down by 50%, you can basically ensure that you will not incur losses, and it is even very likely that you can make a profit.
This is because Bitcoin has a solid market position and strong liquidity; after going through multiple bull and bear cycles, it always manages to reach new highs again. However, once most altcoins crash, they find it very difficult to return to their original prices.
If the altcoins you hold drop by more than 50% or even 70%, the risk of continuing to hold them will significantly increase, and the possibility of losing all your principal will also rise.
Many altcoin projects will completely lose value or support from the community and developers during a bear market, and they 'disappear' before the market can reverse.
If you want to recover your investment, you might consider switching your positions to some higher-ranked, stable market cap, and fundamentally sound crypto assets, such as the top 100 altcoins by market cap.
At this point, even if these coins have also dropped significantly, they are more likely to rebound during the next market recovery, thus giving you a chance to recover your investment.
