Decoin is realy worth investing since they have thier own secured trading platform with 24/7 support and a POS system that entitles token holders to earn annual dividends from thier platform.
Pos system is very useful and in principle opens opportunities for investments for beginners. However there are many sad examples when coins with such algorithm lost the price and died. Therefore continuous improvement in process of existence of a coin is necessary.
I think the team already knows about this, the history of many system with its coins died due to lack of public usage. The only thing to avoid this one is really making it more unique, simple, and improve it to be a better platform.
