Like mentioned by @dirruk. This is a great coin! Good pos-rewards. And excellent trading possibilities at CoinExchange (https://www.coinexchange.io/market/VULCANO/BTC). Works perfect!
Yes, the staking is crazy when you compound it...
Which is 2.6% per day... or 1.3% every 12 hrs...
Compound 1.013 ^ 730 and you get crazy number between 10,000% and 40,000%.
So it's fitting VULCANO is listed on Yobit (and CoinExchange)...
Because Yobit's primary business model is building "casino coins" that pay 1%/hour or more...
But to get paid the degens have to stop sleeping and play dice every hour.
A coin like this is one good idea from going big-time.
