We already know that in a zoomed out to the maximum view of the Bitcoin chart that it's only going up, knowing how the Federal Reserve and the world's Central Banks will NEVER stop printing money. 👀

 - Because of that, I may need to go against my "pleb-nature" and set up another cold-storage wallet just for DCA. I wouldn't like to have the feeling "that I don't own enough Bitcoin". DCA would psychologically help me with that.

Since you said you don't have enough Bitcoin - then you can take it as your urge.
And since you feel that you should have enough Bitcoin and have realized that it is difficult to maintain the value of our assets due to inflation at the present time, congratulations.
There is no need to despair, there is still time to increase your portfolio by buying Bitcoin.
All you have to do is to buy Bitcoin regularly and spend it as much as possible of your discretionary income.
If you think that you have saved enough money in your emergency fund, then you should stop saving money in the emergency fund and start investing in Bitcoin with that money. Buy as much as you can aggressively. Don't forget that Bitcoin may not be at the same price tomorrow as it is today, never think that you will buy when the price reaches DIP. Maybe the current price will be DIP for the next few years.

So buy buy and buy, hold hold and hold
