Just out of interest, DEL has mostly been at minimum difficulty (0.00024414) for a couple of weeks. Right now you could mine it with a CPU. With the network still moving, and the difficulty that low, someone probably is using a CPU.
The coin is dead I think?
That was my point - the network is still moving, so it is still being mined by someone. (Presumably just batesresearch, but you never know.)
