Actually, it is a smart idea if you are an investor or someone who likes to store Bitcoin for a long time with a very large amount. But if your soul is a trader, I think it will be difficult for you to implement such an idea, especially if you are someone who is easily tempted by small profits that come only in a moment. So I think whether an idea is smart or stupid depends only on each person who responds to it more rationally so that their own judgment will always be different.
