People are waiting to buy lower, but what if you're wrong and this is the bottom?
You never know what's going to happen next.
When the opportunity arises, buying low is attractive, but it's not always a good idea to enter the market with that mentality because you'll always be anticipating when the price will be low again. Likewise, if the price of Bitcoin refuses to fall to your price target and instead keeps rising, you'll be losing out on a great buying opportunity by not buying at initial stage. . My understanding is that buying whenever you have the money is the best course of action.
Just accept that no one can predict what the price will be in the future. Anyone who claims otherwise is lying, which is why you should enter the Bitcoin market with a single thought. Cryptocurrencies in general are very speculative and volatile investments. You might earn some x, but you might also incur some losses.
