I think something special is happening here to Ravencoin (RVN) , but please don't get FOMO.
Of course, the good news for RVN is that there is the launch of the Merge tomorrow 2022-09-15 at 6:00 UTC in approx 13 hours frome now. But as it has been hyped since weeks now ETH could crash after the launch. RVN will be one of the only coins profitable for GPU mining so people are expecting a rise to happen here. We should expect at least a correction after the strong upward trend that it had in the previous hours.
