I feel you. If only we're rich enough to buy it weekly or at least twice a week I think it is really a good investment to do for a year.
For the meantime, I am one of those people who will track the Bitcoin price from last year up to the next years
For me, achieving that kind of goal equalizes our winnings and losses in the market. What that means is that, when we buy in a week, we buy what is high and at the same time we could also buy the lows, with this, you can't say that you lose because your investment is diversified in a week when it losses and wins at the same time.
I do really think it helps us achieve the peace of mind on our investment into thinking that we aren't losing but in the end, it feels like we just save money in crypto but the fact is it already returns investments and profits.
