Ethereum just got added to BetFury and the staking page has been updated with the graphic below:
It looks like the mining rates are unchanged in BTC price and remain at 8000 Sats. If you mine with ETH you will receive BFG(BTC) tokens. The mining rate is now stated in ETH which is a bit confusing, but the peg to 8000 sats per BFG(BTC) is still intact. Because the peg is to BTC but the mining rate is displayed in ETH, if the price of ETH/BTC changes then the ETH mining rate will actually change slightly.
These screenshots were taken about 5 mins apart and you can see the ETH mining rate has changed slightly to maintain the 8000 Sats BTC peg. I confirmed this because 8000 Sats at the time was $2.77 USD and $2.77 of ETH was being displayed as the mining rate. This means if the price of BTC and ETH diverge by a lot there will become a more efficient token to use for mining. For instance if ETH becomes cheaper than $2.77 USD per token to mine and BTC becomes more than $2.77 per token to mine, then obviously it will be cheaper to use ETH at that time.
IT looks like the ETH dividend payout ratio remains 90% to BFG(BTC) and 10% to BFG(TRX) holders. This can be seen by comparing the total ETH payout for each token. BFG(BTC) gets 90%.
Overall the main changes are if you are mining BFG(BTC) you now have another token option available. You will also receive a large share of the ETH profit pool. In the short term, we may see a drop off in BTC pool and therefore dividends, as people switch to ETH. In the long term though the ETH pool will build and more people will join so it should start to increase again.
