The trend finally took the reigns in getting bitcoin out to the public in an easy fashion toward investment in icos. The boon that is occurring is hugely in part to all of the business opportunities which are on the table sort of speak at the moment. These opportunities wont last too long at the rate that they are at now. In the future, the only opportunities will be likened to the ones in the normal fiat world where huge corporations and conglomorates gain complete control of every marketplace. This was what happened with fiat when it first became accessible to people in the form of loans and small businesses sprouted. That is now happening with bitcoin. Wait a number of years and watch the same pattern repeat with bitcoin which happened with fiat. Its exciting now, but when theres no more room to grow due to complete control by a single entity, then finance will cease to exist.
I've actually wondered how long it's going to take for this to happen. Right now there are lots of opportunities; later the opportunities might be more monopolized as you say. In that light a great strategy to take as an individual is to find a project within this space that is likely to succeed and then become part of it. In that way, you position yourself to be part of what one day could be a very large company, and that can provide interesting career opportunities and other things for yourself and possibly your children. Of course, if you manage to be an investor in such a project that's even better.
