When he has built strong faith in bitcoin and he has the opportunity to buy aggressively, then he has to do that so that he can acquire more bitcoin within a short period of time since he is still in his accumulation journey, but he should not overdo it, to the extend that he has no funds enough as his emergency funds, otherwise, he will go back and sell from his bitcoin, which has defeated the aim of constant buying and building to Hodli for long-term.
What do you mean by faith in bitcoin and how can it be built? Does it come with having personal experience like investing in bitcoin or checking previous performance or testimony from people who started earlier will suffice? These questions came from the that a lot of people already know bitcoin will change their lives just as it does to others even before they bought their first bitcoin. This is true especially for those who already have idea of the kind of use bitcoin have which makes it far better that other systems of payments. Many people who are holding bitcoin today do not even see bitcoin from that aspect of usage rather they see it from the aspect of making them rich and nothing more. This is why your description of faith in bitcoin got me asking those questions.
