This is how markets work, everybody is after his personal gain. At least I'm honest, I don't ask bulls to buy while promising moon, on the contrary...

But it would certainly be in your best interests to do so. Since you're okay with everyone else losing as long as you gain, why not try to coerce them into your pocket? Would it not make more sense from a profiteer to perpetuate an environment that facilitates gains?
By openly telling people you're going to take their money if they put it in the system, you're effectively killing any possibility of growth. Without said growth a market can decline into death and then your cash cow is gone. Perhaps stemming your greed to the betterment of the system might enable you to reap rewards for eternity instead of a brief moment in time.
What nonsense.
Tzupy's gonna kill the market ... ok, right

Yeh, following that well trodden path whereby the WHALES that move the market publicly advertise their intentions in advance ...
If trading kills BTC then BTC was never strong enough to survive in the first place (I don't believe that will be the outcome FWIW). For now BTC is a almost entirely a speculators market as you well know and until it fully proves it's worth that is not going to change.
Not sure why this riles you so much, unless you are nervous ... there is certainly a lot of fear-mongering in your post at the very least. It reads as more manipulative than Tzupy's post for sure - he's gonna place a bet, and win or lose it, and he announced it in advance. Good luck to him. End of ...
I really can't see the difference in going long/short/leverage/no leverage - it's all a gamble at this stage. Investing in infrastructure/start-ups is also gambling, just of a different nature, different time-frame, but it's a more 'positive' contribution than HODLing by a long shot, which at the end of the day, is basically just sitting on your arse waiting for someone else to make you rich, and no better or worse than (actively) buying and selling on leverage.
KnC is in this just for fiat profits as you told us just the other day, but I have not seen you complaining about their latest venture. Oh wait, that's because it might attract some new buyers to push the price up ... with more speculative capital.
At the end of the day that is not what is gonna determine long-term success. UTILITY will be the arbiter of that.
