I agree. You are very right. It is better to work with trusted projects that have long been on the market. And they have at least some guarantees that they will not disappear tomorrow or in a month.
Well, even proven projects can stop working. If you think so. Say platform Steemit depends on the community of bloggers. But there are too many requirements and new users are not actually added. And that means only one such project can disappear.
