It is great that you are happy to have bought bitcoin for a good price, however I would recommend to you that you never reveal the amount of bitcoin that you are holding to anyone especially to people you do not know, after all while the majority of the users in the forum are honest people there are also a lot of scammers that want nothing but to get to our coins, so now that you have revealed you have so much bitcoin you could become a target to them.
One may need better financial privacy by never disclosing ownership of the amount in public. I can confirm that people who own a lot of crypto asset including bitcoin always to be the target of scammers and scam attempt in various ways and maybe this has been thought of by others so they really practice privacy security both online and offline. 4.5 bitcoin is currently equivalent to the cost of living for several years in my country, so of course it's a bad thing to reveal to people as it would only put themselve at risk.
OP, buying bitcoin when it goes dip is the best option for anyone who knows how the price will recover after that. Price correction can open up opportunities for traders to profit after the market recovers and I've seen it that way many times. If we think that the price correction sometimes reaching 10% is a bad start for bitcoin, then it should never have hit $69K some time ago.
