I really liked comparison you made between learning and earning. It is true that main goal of learning is to use what you know to make money. It is great that you are investing in Bitcoin and doing it in smart way that helps reduce risks. Congratulations on investing over $600 in Bitcoin this year. That is big commitment to your financial goals. I am sure you will keep learning and adapting to changes in market and hopefully your investment will work out well for you at end and you'll be able to remove L and keep E.
I also want to join you, likewise others in congratulating the newbie for the bold step in the right direction. This is a stone bridge that took most of us ages to build despite our familiarity with the cryptocurrency space. It is one thing to learn, it is another thing entirely, to earn. To earn, you definitely need to learn the processes of removing the L which will take time and consistency. I think OP is already on his path to earn and needs all the encouragement and advices to keep up with the good work.
Every good thing starts from a learning process and like you said, when you remove the L from learning you'd start to get the reward by earning. You have graduated from gaining knowledge about Bitcoin to actually investing in it, the next step for you is to secure your private keys. If you're holding your Bitcoin in a none custodial wallet, it means that you're the sole custodian of your coins, if you misplace your seed phrase or it is stolen it means that you your BTC can be in jeopardy. Congratulations on your DCA method, it is the best strategy for average and low income earners to accumulate enough Bitcoin for the long term.
I absolutely love his boldness. It is something that is rare among newbies. Investing your hard earned money into a process you're kinda newly introduced to is a whole bold step and requires a lot of confidence as well. I would have said, you need to be consistent, but it's obvious OP is already determined, disciplined and consistent to have built to this extent. These are the key characteristics of every successful bitcoiner today.
Secondly, I will advise he takes things slowly and in phases. What I mean is that, since he's already building a good portfolio using the DCA investment approach, let him continue to do that on a centralized exchange for now to remain at the safer side instead of just quickly jumping into decentralized non-custodial wallets. Let him take it step by step, until he gets to the level of switching to a non-custodial wallet like Bisq, then securing a seed phrase as well as storing the seed phrase sufficiently.
