When I started with bitcoin, even 200-300-400 usd levels seemed high. Therefore I think bitcoin always seems to be expensive, therefore it really does not matter when you buy it, just aim for the dips and long term.
Yes, bro, I also remember these times. Those men, who did not sell their Bitcoins several years ago, earned millions! Now, BTC is relatively cheap in comparison with 2017 (spring-summer).
