Your question is too vague and non-descriptive, there are many coins with different intentions, ownership, niches, etc. There are some coins like bitcoin which have no "ownership" as far as a company owning the development, distribution and production of the coin. There are other coins that were developed specifically by companies to do very specific things, such as Dash which was developed specifically for quick transactions..

There are many coins which are simply ponzi-schemes that some company thought would be a worthwhile payday. We call these pump and dumps, but if you actually pay attention to what a coin is offering, why a company is developing what they're developing and how they plan to maintain and scale themselves up for mass adoption then you'll be able to pick and choose the coins that have some longevity and integrity behind them. The coins that are empathetic to the consumer/user needs/desires are going to be the coins that survive long-term in the cryptocurrency industry.
