RE:Calculator....No worries about those old rigs, they can easily be replaced by Mackie's A$$.
He watched and posted so many youtubes about Crypto mining that his butt can mine, harvest, generate new coins, all he needs to do is getting plugged in . only dowside is that he gets easily overheated even in cold places like Sweden. HIVE will ask's one of the 5 employees to Apply a cool gel on hard working parts. the number of mined coins easily can be seen trough Mackie's eyes, now HIVE wouldn't be more transparent than this.
