On the chart, I can see that the new was two days old already, bitcoin was $22600 on the chart, bitcoin price today is 20400. Some people may be buying actively, but the bear market is still not yet gone. People can buy now and hold for the next 3 years and make profit though. If anyone is buying now, they should know that the price may still fall but they should continue to hold until they make profit and they should consider this as a long term investment.
Well, that is the whole idea. If history has thought us anything, buying in batches is best because we can't really say for sure where the bottom of the market is. As we most have all seen that the price further fell to $17k+ from the $20k+ you mentioned and that was even a better buying position. The problem will only be having extra liquidity to continue buying at every opportunity the market provides, more like DCAing.
