Is it worth making stub sites for future projects and feeding PS?

Question

Search Engine Optimization

This case is interesting:
There are a lot of ideas for projects, domains have been bought for each, some are already hanging for 8-12 months. without activity (that is, not even registered DNS).
So, does it make sense to make a mini-site for a new project on each domain, perhaps place a thematic text on the main one (+ a couple of articles/news)?
Please share your experience and opinions.
Goal: when the hands reach the project, start already, for example, on a one-year-old domain, and not a zero one.

Answer 1

Until the age of 13, when I was young and ambitious, I also had a bunch of domains. Then I realized that the time
in fact, never will come if you are not doing the project now.
Got rid of this rubbish.

Answer 2

There's a meaning. You buy several domains, let's say with the entry of a key into the domain. You put a mute. After 2-4 weeks you check positions. If there is a site that has risen, you take it to work. Next is the matter of technology. Key entry is very important.
