Actually in this case when talking about investment it is a choice and indeed if we can do it then why not.
Regardless of whether or not fiat is safe at this time we must realize that fiat is the greatest power but investment can indeed be a necessity without leaving fiat because after all for everyday life fiat is still very much needed.
I will not leave fiat in this case because it is also impossible because fiat still has full power, especially to support life but for investment, especially in bitcoin, it is a different story. Do not merely when you are in bitcoin you forget and consider fiat bad because in the end when looking at the situation in everyday life fiat is still a primary factor if categorized as a necessity.
In this part of your post, your ideas sound a little lost Fauderz, even though I think that I understand what you are saying in regards to making sure to keep some feet in the fiat world, even while investing into BTC, and even on a personal level, I don't have any problem with the idea of keeping a foot in both worlds, but your comment's seeming attachment to fiat seems like it could be a bit problematic, as if you don't really understand what bitcoin is offering..... but from the rest of your post, I can see that you do seem to understand that bitcoin is a potentially powerful investment.. so what is it? Do you consider that there is anything wrong with establishing a bitcoin position and continuing to operate in the fiat world, so it is not like your choice to invest into bitcoin would result in your having to have to give up fiat? You seem to understand that, so why be so lovey-dovey in the way that you describe fiat? Sure fiat exists, but we don't need to be lovely-dovey about fiat, since fiat has a lot of problems and hopefully our investment into bitcoin allows us to have some non-correlated exposure to money that is not so controlled and manipulated by state actors, who might not even have bad intentions but the system that they are working within has gotten away from them, so they have to engage in deceptions, lies and desperations to try to keep normies trapped into such a controlling system.. especially ways that fiat is currently being manipulated to control people, which maybe had always been somewhat true and the powers that be do not really like normies using cash, either.
No, my point in this is that we don't have to hate fiat and not be in it because we still need it for our daily needs and indeed until now I still have a dependency on fiat (to support my daily life) so there is no need to feel that fiat is a mistake and btc is right because at the end of the day their concepts are opposite but it's not a search about the truth because I think both are right but their functions are different for me.
Bitcoin I use as an investment tool for my future but fiat I use to support today's needs. As long as both are still useful then I will continue to use both so there is no concept of wrong and right between bitcoin and fiat and they are also made not to blame each other.
Therefore, we must have a careful strategy from the beginning so that in the future the needs we need and the ongoing investment (DCA) are not disturbed. 20 percent is not the initial benchmark because if in the end if we are not able to be consistent in the future, why force something that is difficult for us to guarantee so that initial management of finances and planning in investment must be decided carefully from the start.
If we set too much from the beginning, for example 30 percent or 20 percent but are not able to be consistent, it will also be not optimal so it needs further emphasis on whether we are able to invest with an amount of 30 or 20 percent for the long term or not. If in the end this is burdensome then reduce it so that you are able to be consistent but on the other hand you are also able to support the needs of the life you live.
I agree with everything you say here Fauderz, and I would just add that it is likely better to find an amount that is sustainable that is lower than to pick too high an amount, but at the same time, if someone is really on top of their cashflow situation (and they have an emergency fund in place and have even projected out their cashflows for 6-18 months), they may well have enough information about their situation to really be aggressive and to push their DCA to its maximum amount every time they get paid or every month or however they have it set up and decide to fluctuate every paycheck between 10% and 30%, so it is not like they have to be exactly consistent, and just because exchanges allow people to set up automatic DCAs, I am not really much of a fan of the automatic DCA, yet at the same time, many times in the real world, people don't want to have to manually make their BTC buys on a weekly, bi-weekly or monthly basis.
This is a good point and I like the addition that you gave and thank you for this because I will probably add this also as a strategy that I do for my support when investing because what you said makes a lot of sense and I can still do it.
Because indeed I still feel for now rather than we force trying to buy too high but instead it interferes with other needs it will actually make ourselves not be optimal and will actually mess up the initial plan so it doesn't matter if the DCA is lowered a little like 10-20 percent but it can guarantee you are able to do it well rather than forcing the will with 30 percent as a benchmark but instead it ruins the scheme that you will make for the future.
