I understand how they feel since provably that they think its a waste of opportunity for missing out to buy Bitcoin before that's why he release these sentiments and confused about if he's late for buying Bitcoin now or not.
Actually if he act the same way back before and doubt to start provably this is the second time that he would say those statement especially if Bitcoin pumps again. So better he should erase those thought's about he is late to buy Bitcoin, but rather he should do some good action and start to accumulate now. The huge risk for upcoming dumps is for traders and for sure that they won't get any huge problem if they just decide to buy and hodl their Bitcoin for long time.
I am not a fan of buying in a bull market, especially if you are a hesitant person, because in a bear market you may want to sell, especially if the price drops enough, as it happened in previous cycles. And not everyone is willing to hold Bitcoin for long enough, often weak hands can change their minds in bear markets when it seems like everything is really bad. On the other hand, there are companies that are buying Bitcoin now and they don't seem to care that the price is so high, it means they believe that this is a fair price for Bitcoin, and they are willing to hold it for long enough.
