Yea, I think I will agree with you on this, buying Bitcoin is not actually hard but what is hard is, getting a good source of income, knowing the right amount to use, investing consistently and holding for a long time that is not always easy most people find it difficult but those who are determined can do it.
Buying Bitcoin is hard is just a consciousness of our mind. If we have the resources, the income and we know how to budget.
The usual reaction of our mind is that buying is hard because we've got a lot of expenses. But you know what's hard, the future of ourselves that we have missed buying when it's still quite low.
$100k per Bitcoin now? in the future, what it will be? $200k, $500k or even $1M?
That hardship is just on our mind and we have to beat that by doing the initiative of buying it asap. Once it has become a practice to DCA, we'll thank ourselves later.
