If you look at the capitalization of the entire crypto market (currently more than $1 trillion), it seems to me that this won't be a big problem for prices. Moreover, there will always be those who will buy at cheaper prices, this will happen sooner or later. Perhaps even in 2024, after the Bitcoin halving, which will be the reason for the start of a bullish rally. This seems to me the most likely scenario at the moment.
I wouldn't want larger Bitcoin holders such as MicroStrategy, who control 152,800 BTC (which is equal to 0.7% of the total BTC supply) to sell. If several of these large campaigns sell out in a short period of time, it will be a nightmare.
Indeed, there will be an impact on market prices, but this will not last long because as we know, ahead of the Halving, people will take advantage of cheap purchases this year. So if this scenario is implemented and FTX sells every week, of course investors who are waiting for momentum will not waste this opportunity. I quite agree with you, large institutions with Bitcoin holdings will control the price but there is nothing we can do but follow their lead while being part of a small percentage of Bitcoin investors.
