Look, this is the bottom line. In business you should never change a deal you already made. Period.
I have run many companies (50m plus), and I have made many deals I did not like. But I always homered a deal once I made it.
These guys caused the exact opposite of what they wanted. They wanted to attract new miners and create trust and loyalty. Heck, I was even thinking about even staying longer term (have over 100mh). But I will never do business with them again. They have no integrity
