Yes there is no definite time or position where you can consider buying bitcoin but that's why there is technicsl analysis and such indicators for you to analysize when is the good time to enter the market, you can't just buy and buy without thinking, even you will going to do DCA you should consider the down and up trade, is better if the bitcoin you brought will only goes up in the long run, I notice your account to be a newly created, believe me investing or buying bitcoin is not that simple, its easy to say you should huy bitcoin and its easy to buy bitcoin, but in terms of earning bitcoin it will be hard road because you will need a lot of patience and dedication in order to leanr how to earn in this field. But yeah, stories like the OP are one of the stories that encourage us that investing in bitcoin will never be too late.
