Looks like btc should be purchased right now because if the price of btc starts to go up now then $40k will be very easy to design. Moreover i would like to say that it is more risky because if the price of btc breaks down again then you can fall into big loss. I think now is the best time to trade because now the price of the best token is low so you can start with little money.
Currently it is worth buying half of the assets that have been added to the portfolio, even though you have chosen to buy BTC but our target must be to buy at a lower price, my prediction is at a position below $25k maybe the right time to buy assets in large quantities.
