Better if you buy more bitcoin now and you will earn a lot of profit. But in reality we don't know what is the next of the bitcoin if the price are goingto down or to pump depends to us.
There will be a need to more good news and acceptance by many countries before it pumps again. Like what happened last year, today there are things that considered in crypto that makes it complicated to pump.
Losing a lot of confidence in the crypto market will make it even harder to pump again in the near future. But if the ETF goes back well, I'm sure the market will recover soon. I have also read several articles that say this decline was due to something like that. There is no need to rush to buy for situations like this, because I personally believe prices will still go down again, if buying too fast it will only make you panic and worry, so wait until there is good news someday.
