this is why, buy at a price where you feel you have the advantage of. because no one can predict the lowest price. you are just relying on where the market goes. if you do believe that bitcoin will have good future, even at this price level - 20k+ is still good to slowly accumulate some.
Yep, everyone has their own target and their own analysis to determine when to buy.
I don't blame those people who want to buy at $20k, it is their own right to buy. But for people who want to buy at a cheaper price, there is nothing wrong to wait for the next dump. Although no one knows the bottom in this bearish season, BTC price is very possible to drop more if we consider some factors. However, it is just for people who believe we don't reach the bottom yet. For people who think the bottom has been reached, they can ignore it. Please buy Bitcoin based on own analysis, DWYOR.
