Revenue - current estimated revenue (now)
Revenue 24 - past revenue (for the last 24 hours)
Percentages are relative to Ethereum, Ethereum being a constant 100% at all times for any period (that is why it is highlighted green). Everything is compared to Ethereum basically. Current profitability is present, the other 3 are calculated from past (stored) data. You can see movements and trends using these.
There is no prediction whatsoever on whattomine just pure good ol' stats.
@fonyo, thank you!
No worries matey. Bear in mind, Ethereum's price is not constant so sometimes it is a bit tricky to see the aforementioned trends & movements. Luckily, Ethereum's price is quite steady and stable except for the spike in the last few days but it is still a better option than comparing everything to BTC for example. When the spike was materialising, some of the stronger, more profitable coins seemed to have their profitability dropping but that wasn't the case, it was Ethereum rising heavily. In Ethereum we trust...
Hope this makes sense.
