I would not buy bitcoin now, because bitcoin is too high in my opinion.
If you already accumulated enough bitcoin (or more than enough), then you are in a position to wait.
If you have not accumulated enough bitcoin or more than enough bitcoin, then you might need to consider continuing to accumulate. Of course, since you have been registered on the forum since 2017, you may well be in a position in which you have accumulated enough or more than enough bitcoin. . That is surely for you to figure out.
Exactly, I think he has already accumulated a lot of bitcoin earlier before now maybe he wouldn't want to take the risk to invest in bitcoin now that the price is expensive. It might be that he hasn't even accumulated enough bitcoin probably just waiting for a dip before investing. Though everyone is entitle to decide when to invest and when not to invest it actually depends on your choice, for me I don't think if there's any perfect time to invest in bitcoin as long as DCA method is involved.
if you're waiting for a dip in the price, probably you will just wake up one day to discover a deep increase in the value. at this point what will you say then, are you still going to keep procrastinating? I don't mean to force anyone whose mind is already made up, of course if you choose not to invest due to the high increase in the value is fine as long as you're making the right decision for yourself.
