Simply stack Bitcoin if you have the means to do so.
I mean, paying yourself first, which includes setting aside a fixed amount of money to buy Bitcoin, works like a charm for me regardless of the market conditions. In my case, every time I win an art contest, receive my signature campaign payout, receive my monthly salary, or get paid for some freelance commissioned artworks, I make sure that every penny that fills my wallet automatically increases my Bitcoin stash.
No chart or any sort of noise. Just following a strict budgeting religiously.
The OP did a good research and presentation on the various plans to accumulate Bitcoin as well as how to handle situations that might make one lose focus. For me, bitcoin accumulation is automatically embedded in my income. What that means is that when my income increases, it will affect my bitcoin holding but a reduction of my income will make me buy less. This is just my simple method because I don't have much idea about market analysis or the use of bots. Looking at the market condition can also lead to FUD, this is why I don't pay much attention to it and just focus on my accumulation plans. My profit margin is not too high to avoid missing out. I will sell some part of my coins when it gets to my target and keep others for the next phase of my plans.
