Anyone who wants to ensure the ITO funds aren't refunded can place buy orders above Bittrex's buy wall
If you want to minimise the risk that we'll not make the minimum threshold, outbid Bittrex!
You just made me sell my 10 BTC BLOCK with this one
This entails that you bought block but don't want the Blocknet to launch.
(Or at least, that you want to increase the Blocknet's risk of not launching.)
Which is irrational.
