Can you imagine what price decline will take place when Tierion holders start to convert their TNT to BTC due to hard fork "free coins" ?

It is going to go far deeper into red numbers than before.
Discl:I don't want to spread FUD, I am also a tnt holder
I actually don't think that its going to drop that hard. There are nearly no buy orders - so you would have to sell in a huge loss.
Nevertheless I am putting a buy order at a very, very low price.
TNT will come back up.
