Here is a Great Way to Dollar Cost Average.
If you would like to DCA (Dollar Cost Average) into HEX Crypto then I recommend using the Staker App. It is the easiest way to buy HEX with a credit card and stake it directly on your phone. Here is my affiliate code. https://staker.app/invite/Fc6C
If you are not using the DCA method to buy crypto then I do not know how you can be successful outside of getting lucky. If you are very smart you might be able to chart your way to success but I am not one of those people and most of you are not as well.
