OK DUMBASS, why would the engine allow that buy order to exist in the first place? Unlimited KHS/MHS in the trading engine? Obviously it's a buy order but guess what if you go to Hashnest and try to buy 300 Ph/s worth of shares, IT WON'T LET YOU. Fancy that. Their orderbook limits you to buying what's available on their marketplace.

Any explanations for this, or shall we add it to the list of things you make up and can't substantiate?
