I strongly believe in future Bitcoin price will hit $100k, $200k even more. So till now it is not too expensive i think.
This is the target of most bitcoin holders at the moment, I am also targeting $100k as the new ATH that Bitcoin needs to achieve.
At the moment the price is still at $51k and this is also close to the last ATH price ever reached., it is already a remarkable achievement and the price of Bitcoin continues to strengthen.
Doing DCA is indeed good advice, because the price will still fluctuate, and the price will correct at a certain level.
Waiting for cheaper prices is also better, and that's bound to happen in the near future.
Going down doesn't mean bitcoin doesn't have a pumping machine anymore, but a drop will result in a tremendous rise later.
