ETH is never, ROI on bitcoin via hashflare with difficulty adjustments is looking to be 8-9 months at the current rate.
You are wrong. Bitcoinmining might have died 5 minutes ago, read the post on the Hashrate, i have spoken about what i think is chinese manipulation of hashpower and difficulty to sabotage bitcoin blockchain, blocktime, senderfee, and ultimately the collapse in price for bitcoin, i never saw any support for my theory here, but after latest increase, ROI went negative, so next rise in difficulty will not make it better.
