So I don't think it's time to buy more BTC currently.
Firstly, there is no invitation to buy here. If you have Bitcoin hold it. If you want to increase the load, just buy it, it's up to each person's choice.
DCA is still good just for an assurance to accumulate more right before bitcoin reach above 40K level. You’re right that this current bullish trend might collapse anytime but I believe the price will still recover at some point since there’s halving next year which is one of bearer of positivity in Bitcoin.
Yes, even though there is a decline in Bitcoin prices, the 4-year price movement circle after the halving will bring Bitcoin prices up again. Actually there is no harm in buying Bitcoin at a price below the previous level.
But again, it all depends on our own choices. Whether you want to buy it or not.
But for sure many would provably doubt on current situation since although we see some good pumps happen for BTC recently still they are afraid to experience a bull trap since some people talk about the possibility that it could happen. That's why if we are really into investing on bitcoin maybe at the moment we should never look for short term since it will never result good to us since for sure that we will experience to see a lot of correction so better accumulate then hodl until next year to see more better result. But still its up for the investors preference if they could able to wait for long time frame since not everyone have high patience to wait for a year since majority of investor want a fast profit. For now many people speculate good about the halving so there's a huge chance for holders to gain from its effect or hype that could bring to people when this season occur.
