I think there is no need to wait for investing in Bitcoin. Because I myself bought Bitcoin when it was 25,000 and sold it at 40, thinking that this might be the highest price.
If you buy at 25,000 and sold at 40, you're not worthy to be called an investor but a trader because what you were doing back then is short term investment and not long term investment is only when you're into short term investment that you can easily be moved to sell or having the feeling that $40k could be the final ball stop, did you even make research before investing into bitcoin or maybe you just pick interest in it and start investing into bitcoin when you don't even have the basic knowledge....I think this could be the reason why you were just making exaggeration back then.
