I think Raptoreum is still profitable for people with cheap electricity. I don't use my CPU's anymore as im going to €0,42 a kw in the coming period.
I tried mining Raptoreum using my Ryzen 3400GE and I got 89-120H/s hashrate, I minted for almost 3days but it seems my hash is not enough to mine RTM, and my projected income is 1.9 RTM in 3 days mining, and the minimum cashout is 10 RTM is some of the mining pool. I think AMD ryzen is not the best contender in cpu mining.
Actually Ryzen CPU's are the best for mining raptoreum. But a 3400GE is pretty low grade. Try a 5900X or 5950X and it's a whole different story.
