Why does the Raspberry Pi Zero not have two working USB ports?

Two USB ports would have needed an extra USB hub chip on the board (and there's no spare room for that). The one USB is directly connected to the ARM processor (which is why it can do USB OTG). With ...

RPi zero ethernet connection via HDMI port using a HDMI to RJ45 adaptor

No. HDMI to Ethernet adapters are used to send HDMI display data over an Ethernet cable, rather than network data over HDMI. This won't work.

Creating a Raspberry Pi Zero cluster for crypto mining

You wouldn't gain any extra magical power, as you can't create more energy than you put in. It would just be a maximum of the power of a single Pi multiplied by the number of nodes in the cluster. So, ...
