The price of Bitcoin of a truth is very unpredictable but considering the past events in the Bitcoin market, buying Bitcoin when there's a dip have in most times been very profitable to investors. It's important for investors to have it at the back of their minds that buying dips doesn't guarantee profits but the truth is that it's more advantageous than buying when the market is experiencing uptrend movement in price. In as much as I agree with you that waiting for dips have it's own mental pressures I also want you to come to terms with the fact that it's better to always buy dips than buying when the market is on the high. Buying dips to me will always be the perfect moments of investing in Bitcoin and unless the market leaves me with results to think otherwise, I'll continue to stick with that
When it comes to buying Bitcoin, the level of courage of the investor will also be tested so that they will all make options for themselves when they want to buy Bitcoin in certain conditions like you said for yourself where you only dare to buy Bitcoin when the price is down and do not dare to buy Bitcoin when the price is up for certain reasons. But if we look at it further, of course investors who buy Bitcoin when the price is increasing are also not wrong as long as the Bitcoin they buy is not to be resold in the near future. This means that the investor will sell the Bitcoin again after holding it for a long time or when the next big increase cycle occurs again in Bitcoin.
