During the past two-three weeks, the exchange rate of altcoins such as Bitcoin Cash, Bitcoin SV, Ethereum and Litecoin have fallen heavily against Bitcoin. So there is a real possibility that some of the miners could have shifted from mining altcoins to mining Bitcoin.
BCash and BSV miners shifting, sure, but not Ethereum and Litecoin due to the difference in algorithm and hardware needed.If you check the BCH/BSV hash rate, they are either showing a stable difficulty or a declining trend.
BSV has actually made a massive jump in the last 5 or so weeks. It went from 0.4Eh/s to 0.9-1.1Eh/s. BCash is the one lagging behind, but I'm pretty sure that Roger and Bitmain will organize a pump to bring the ratio back to 5%, which seems to be the ratio they are comfortable with. It takes time for them to accumulate enough BTC through mining to have enough to pump their shitcoin by 20-30%.During the last 4 weeks, the BSV mining difficulty has fallen by more than 35% (from 210 G to 135 G). But you are right, prior to that there was a sharp jump in the difficulty. But these figures look abysmal, when we consider the difficulty BSV had at the time of its creation (somewhere around 600 G). The reduction has been in the range of 4-5x.
