Buy when others are fearful

Currently, the Fear & Greed index is at 22 (Extreme Fear) and many of the crypto assets are
undervalued (meaning the RSI14 is below 30). Take the bear market as buying opportunity and sell when everyone else is buying.
Whales and old investors did this and were perhaps happy when there is panic selling happened in the market as in this way, they make money from them. This is not the thing it appears to the mind of a doubtful investor but absolutely full of worries and negativity. As long as there are people who are weak and never understand the market volatility, this will have a no-ending story and we keep seeing a high Fear index.
Well, the reality is that;
some are selling at low prices and whales are catching them.
