It's a pump bubble. No way Multipools are generating over $1 million.
This happens each time Bitcoin and all the alts decline in value - some random coin is selected and everyone throws dumb money at it and then people are stuck left holding the bag. It has happened several times in the past 90 days.

I respectfully have to disagree. BlackCoin was increasing in value way before BTC started declining. The increase in volume and market cap has to do more with promotional efforts and key partnerships with some of the top companies specializing in crypto-currency.
Also I would like to point out BlackCoin is POS not POW. There are not millions of coins being mined every month, so when a dump happens it is minimum at best. Why? Because a large percentage of the coins initially mined were dumped weeks ago, and the coins being traded now are mostly coins investors purchased. As the value keeps increasing people buying at this current level and above will not want to dump and suffer a loss. It will be a few days or even weeks before we see a brief slow down or retraction.
