I am planning to close the iSpace pool for this coin ..... any reason why I should hold off?
Short answer : No.
It's really interesting for me why 42 coin had a great price and big market, but 21 coin didn't. I'm not anybody from its team, just mined it for some days. I understand the philosophy of both - the devs though: "if everybody is creating the coins that are mined hundreds, thousands, millions, billions or fuckilions a day, I will create the one, that you can mine only small fragments of coin". Makes sense.
Just wondering now why this worked, and that - not.
