Hive team is asked to implement this or that miner almost every day.
Here I will explain why we don't do this until it becomes popular.
Please look at the above screenshot. This coin gives +30% profit comparing to ETH at the moment I write this. tdxminer is doing this on RX cards. Great, awesome.
Our 8 GPU rig gives 22 Mh on lyra2z algo. Total nethash is 204 Ghs (204 000 Mhs). So there is around 204 000 / 22 = 9200 miners. THIS IS THE WHOLE NETWORK FOR THIS COIN!!! Roughly 10k miner at most.
So the guy who is asking "please add tdxminer" does not have calculator or understanding what will happen next. We need just 3k miners more to get your profit down to ETH profit level. -30% from XZC profit. So asking to add this miner is like to enjoy your food alone and then call for friends and shit on table.
Mine it alone until everybody find this gem. Be happy.
And we already have a past story with lolminer and optiminer. Remember the hype with MNX coin? Hive chat was terrorized with "oh please god add this super profitable miner". MNX difficulty raised to the sky after a week Hive added it. optiminer is now used by 0.01% of all hive users. One hundred of percent!
So please be careful with your desires.
