The best investment strategy is to get lucky by investing in one project. You can, of course, play it safe and choose several projects, but you shouldn't waste your money on dozens of projects. I usually choose one, maximum two. I choose wisely for a long time, because it increases the chances of making a profit and not a loss. And then I get profit most often. I have been on the market for a long time, at one time I made good money on bitcoin, so I have money from which I can cover the losses if something happens and put them into a new turnover.
