It seems very true when other people are afraid of something that we can become greedy and dare to take risks. take the risk and wait till you gain what you deserve because of it, I think you really should take advantage of it because sooner or later crypto would recover.
But to buy at falling time needs lots of other calculations compared to being greedy while rising markets. I guess it may not possible without some knowledge on predicting the turning points of the markets. I guess it may become a practice but need some more time to understand the essential of this strategy.
As much as we can see buying to happen in a day or more time frames, we can also see accumulation in fewer time frames. However, with the volatility of the market, sometimes, it is always best to stay relaxed than expecting something to be a buying price level and then seeing a fake beak out. Most times, the volume on break out is always the easiest way to detect anyway.
I was a big fan of Warren Buffet some times back but unfortunately I had failed to predict about the futures of cryptos and especially bitcoins which may be the reason I am always hesitating to follow his golden words in real life and more particularly in my trading.
