You can do it when you are really ready to do it. Just like this, just put your level of confidence in Bitcoin first, because if you can't control your lust for the profits that come your way, then you are not ready to enter the long-term investment zone like JJG did. I see almost everyone doing DCA for their long term investments but they don't have a strong mentality to hold it in the long term because they exit when they are already making a profit.
I think you have to learn step by step first to prepare yourself mentally for long-term investment. DCA really supports you in accumulating BTC in each Quartel if you make purchases in each Quartel, but you have to have a level of confidence in the long term early. So with what you said it seems like you are still waiting for your salary from your office to buy BTC. of course that is a pretty good decision and I think do it based on the percentage that you have, divided into your financial interests for living needs and for investing in Bitcoin.
As nothing is actually ever simple in this world to do especially when it comes to field of financial stability same thing applies to actually successful holding your Bitcoin and it's another case if you are accumulating through DCA, why? Well because it's not an easy task and most people actually just give up at the long run of it because of so many reasons and here are some.
---lack of discipline
---wrong financial income or none at all
---No proper planning
--- procrastination
--- impatient
Before anyone can properly practice DCA and still hold on to their investment for a long period these certain barriers are to be broken.
Everyone who has decided to invest in the long term of course has planned well in advance. So in my previous review I said that they must be ready to throw away their thoughts/desires to take advantage quickly because if they can't do that, then the list you mentioned will not be in line with what I have mentioned. The list of items mentioned is a basic list that they have prepared to run their investments in the long term. Well, like the financial aspect (JJG has said that if you can't allocate $100 for investment every week then you can reduce it by adjusting the income you get). Another interesting list for me is the level of patience (patience is the main principle that they must have every time they invest, whether in Bitcoin or other investments, because achieving success is always accompanied by patience).
So on other points it won't have a big impact, because if you are not disciplined, it won't be a big problem because we make purchases in stages and if you miss 1 stage level it won't be a big problem because you can continue at the next stage.
