We just need to know how to buy it and how to store it in our wallet.
In the beginning, you might not even think of learning about wallet because since you are using DCA to buy bit by bit, you can store your bitcoin with a third party like exchange so that you can continue accumulating it in the exchange and continue reading and learning which self custody wallet is suitable for you to move your bitcoin into when the amount have increased to $500 and above. This will enable you manage your UTXO proper for the future in order to avoid paying very high transaction fees for too many small small UTXO of $50 dollar each.
Knowing a good exchange to open an account with and buy bitcoin from there is the what is necessary. Another thing is figuring out your discretionary income and knowing the amount that you can be using to buy
What we need is a constant stream of income that goes straight into Bitcoin and that stream can be income generated either from signature campaign or through some other part time job. In this way, our monthly income can be used for our daily living while the extra money we generate goes straight into accumulating Bitcoins. In this way we can maintain consistency in accumulating Bitcoins and also hold them for long duration like 10 years or more.
What if you have a discretionary income from your monthly salary, are you saying that you wouldn't invest with it as someone that does not have another means of income. Everything is a gradual process because if you already have a discretionary income, you shouldn't wait and start looking for a second means of income but start investing right away so that, as you are investing, you can be looking for a second means of income to increase your discretionary income for aggressive buying.
