I wanted to buy BNB when it was $15. But I didn't buy it, now it's too late and expensive
The time to buy BNB at the lower price already gone and you must move on to the another coin dude. there's no reason for the price of BNB to go down again and this will never happen.
I have been buying small amounts of BNB at that time.
Im also regretting my decision not to buy BNB when it was around 1k.
I should become another millionaires now.

BNB right now has a market value of $299 and it was too far from the dump value of $15 which is of course a right time to take advantage to buy BNB if ever, but then it already passed and i guess it wouldn't go down at that value again. Though, there were still some good altcoins that possess a good and worth to invest with like DOT but yeah, i had some sort of feeling like yours that you should feel lost about it because BNB was a worth it altcoin.
