Greenidge Generation Holdings Inc. runs an integrated cryptocurrency datacenter and power generation business model.Management expects to have the first phase of the Spartanburg's project to be closed in the second half of 2022. Sales could pick up in the second half of 2022.With the cryptocurrency mining market growing at more than 28.5%, in my opinion, Greenidge Generation will likely deliver sales growth and free cash flow in the coming years.The company is not for everybody.
