I heard that mining helium is more profitable than mining Ethereum with graphic cards, it's such a shame that I can't buy a helium miner because it's not supported in Africa countries as we speak, it's a big shame as I waited over and over for support but no luck
You just have to pray that more people adopted the network and spread the network coverage in Africa. I just checked out the
network coverage and I can see some hotspots in South Africa though not yet concentrated but it's surely growing. I think it's much better than It could have been 6 months ago so If you are in the South African region, you be able to mine some HT soon
