What exchange(s) was ETH on when it blew it's nuts?
Um, "its", not "it's".
Sorry Mal, Crypto Cruiser had it right... you use the apostrophe when talking about possession... and ICN possesses some mighty big nuts.
I used to get rapped over the knuckles with a ruler by Mr Fitzgerald when I got this wrong at school... hence my pedantry.
Sorry, sussex, I stand by my statement. Yes, you DO use the apostrophe when talking about possession - UNLESS you are using instead of the actual noun the word "it", which is an exception. See Rule 2:

Also:
Technically, "ICONOMI's nuts" or "its nuts" are the two correct ways to denote possession of said nuts.
English is a crazy language.
