Are there real projects that don't raise money through ICO or other and still survive just like bitcoin?
Yes, in the crypto space, there are many such projects, and you are not mistaken, but the successful ones receive strong interest from the community. And they thrive when they receive additional growth funds in a variety of ways.
I think such projects should be the target of most people because those are the projects that struggle for real or am I wrong?
But in my opinion, there should be more reasons to look at a project, because at the moment, there are not many such projects appearing and following very complex approaches. For example, projects that are retroactive have one thing in common: they are all based on their time in the market and generating revenue on the platform they build. And the previous non-ICO projects have many successful projects, but will we look back and trust them? Only a few will approach this in such a way.
