It is possible that it is now like this: the market has known for at least half a year that a new buyer will join today, so for half a year everyone has been buying in anticipation of that. Now they can start to realize profits, meaning sell, and the price of BTC will drop.
The question is whether there are more profit takers or current buyers through the newly opened doors - namely ETF.
For at least a few months/weeks, there will be a surplus of profit takers, and then panic sellers when the price finally drops. Only after that will we return to growth. Technically, a correction is also indicated because we practically pumped the price from 26k to 48k without a significant drop
