$COS is the coin of the Contentos project, which was created for decentralized exchange of digital content. At first glance, the idea is interesting, but there are nuances:
1. Volatility - the price of COS jumps, like most cryptocurrencies.
2. Competition - there are many similar projects, and you need to see how Contentos will develop.
In short: the coin is still alive, but whether to invest or not is up to you.
