If you wait 6k correction to buy again bitcoin, then you may not be able to buy bitcoin again at all. Say it corrects to 6k, so what now? Did we expect to rise the price again. If that so, perhaps there will possibly some attacks happened on bitcoin network and everyone including institutions are all selling and backing down unto their portfolio to avoid further risk. Perhaps that's the case if this current price will drive back to 6k, IMO.

Well the best thing to do right now is somehow accumulate bitcoin or sats of it and hodl until you need to withdraw. But don't sell all out. The best hasn't yet to be seen for bitcoin despite ath. Perhaps it can go further to 50k next year or so.
