Considering the fact that you intend having a long term investment, i will suggest that you buy, knowing that whenever there is a drift in price, it will eventually go back up. Also, considering the fact that the market is currently at a support range, i think you should buy.
I understand that from an investor perspective outside of this story, we can see the value of bitcoin has dropped quite a lot and recently, the extreme resistance at the current price is relatively large, that means this may be a time to buy but with the mindset without pressure, our thinking is sometimes very subjective, we forget about the probable incidents. That would be very harmful for people who hear our opinions, and for their good, we should let them listen and think from their own perspective.
