There really is no reason to buy more AVAX even if the price drops further. As far as I can see, after every quarter, a part of the coin will be unlocked and the price will continue to decrease.

In addition, I have not seen the AVAX team confirm the buy back token, so the value of AVAX may drop even more in the near future. If I buy AVAX then I need to wait for good news from them. For example, buy back token and burn to increase coin value or perform Staking liquid pool. That's the news I have come to expect from Avalanche.
