people think like that and prepare their assets before it arrives. however, the potential for halving to achieve high prices is enormous. that can be seen from the previous halving, especially in 2017 when bitcoin prices are popular. if there is good news, it will also be a supporting factor for prices to go higher even if they don't reach the price of $ 20k, I still believe bitcoin prices can be very high.
Will you buy BTC before the halving，like from now?
Well, I don't want to explain this, but what you need to know is, most of my assets are currently in crypto form, specifically bitcoin. I do this to prepare for halving, and believe in the potential of bitcoin. if there is another chance, I might try to get a large amount of bitcoin before halving occurs.
If you already pick all on crypto, i think you must really confident with your investment. Actually out there a lot of people do same thing as you and include me, big part of my investment is bitcoin and i really wait for halving. Maybe if halving really bring good price of bitcoin like what it did in past, a lot of people might be can take profit from it.
