Yes. I think this is a reasonable strategy. And actually, when I read the topic, what came into my head is exactly what you are narrating. One reason why this is a good strategy is that you end up selling at different prices. So if Bitcoin is 100k CAD, and you sell the quantity you said, if it happens that the price goes to 120k CAD, you’ll sell again and you will not feel left out of price increments because you are gradually selling.
If you are a long-term holder of Bitcoin, you can earn in the future. The only strategy to do is hold Bitcoin and nothing else. So I don't understand what other strategies op is talking about. Because if you are not a long-term holder, you will enter in the short-term to get a profit.
So that means it depends on the choice we make as a trader or investor or holder. Maybe it's just that easy so that we can easily understand these situations.
