This is what I've been advocating for, going all in ordinary is not a bad concept but it is most appropriate if you invest an amount you can patiently hold on to because is a long time investment, moreover even when you do your research on most of this other coins, how reliable and sustainable can most of them be, so Bitcoin for me remains the undisputable coin.
However the idea of "going all in" can best suit people that have understood the market navigation and have the good financial muscle to invest and hold, at this stage they've taken all precautionary measures to reduce their losses and increase their gain.
Maybe it's simpler
1. Buy and Hold and there is no need for advanced analysis if we buy with DCA.
2. Increase the allocation of funds for the next purchase if you earn more income at that time.
3. To achieve routine purchases in stages, you have to concentrate and not be consumed by fud that make You feel anxious or anything that can hinder long-term investment planning.
4. Have at least several options, Including reserve funds, to be able to accumulate Bitcoin when the price of Bitcoin drops suddenly.
5. put your own principles first in planning your investment because if You are unable to implement several options in distributing funds then it is better to buy regularly at each stage that you have planned with DCA.
6. Mainly hold bitcoin in a personal wallet or in a wallet that you control the keys to.
7. If you are married, It is better to tell your wife or children that you are investing in Bitcoin.
I think if we are consistent we don't need many ways to make long-term investments, We can just Buy and Hold until the investment target is achieved, For example 10 year. Moreover, for example, those of us here who are not very skilled at reading chart, Of course DCA is the best in every way. maybe my advice is to stay away from Shitcoin and focus on Bitcoin only.
