I think we are already in the dip and Bitcoin might not fall much lower than it is right now before the next bull run begins, so now seems a good time to buy Bitcoin for a cheaper price.
Nobody knows if bitcoin price will still dip further, it might. But the reason to buy now is because any further downtrend would only be an unrealized loss if the buyer do not sell, and the price will later increase and reach all-time-high. That is the reason it is wise to buy bitcoin now. Some people can even go for the DCA option.
So if anyone buys bitcoin now and the price started to fall, the person should not panic but wait and the price will increase back and later all-time-high will become a reality again.
