I agree with you on this, every bitcoiner has to set up emergency fund irrespective of their financial status, setting an emergency fund is not only for the poor it is also for rich, because having an emergency funds will enable you run a smooth investment as a bitcoiner, be you rich or poor. And i can never encourage nor advice any bitcoiner to ignore emergency because of how wealthy they are, because they need it to run there bitcoin investment smoothly.
It is true, Emergency funds are more prioritized to be managed because with emergency funds our investment journey is not disturbed. By planning well, the investment journey will be well directed.
For those who are just starting out, don't be afraid to keep buying because starting directly is better than continuing to delay, managing discipline by making regular purchases is certainly better for us beginners. What should be avoided in investing is anxiety about the price because if you are anxious you do not have a strong mentality to hold bitcoin in the long term.
