Yes, if you have money then always wait for dip in the market and try to buy at low price and after when market in high you can sell and so you will make profit.
It's literally buying low and selling high. As someone who's always prepared for the market dips, you should be determining which is the bottom and which isn't.
People are always panic buying and panic selling, because they are afraid, for being too careless on buying or selling. Those kind of people are just riding the hype, because their friends are making money in Bitcoin or in other cryptocurrency by "buying low, selling high" they also invested their money on it but doesn't have any idea on what price to buy.
There's no way to stop those people that are riding the hype. There can be choices for them to make but the situation isn't good for them and chooses to panic sell and just join the hype while they're seeing that they can take advantage of that moment.
