While I respect your support for your chosen coin the idea of having ~400btc on an exchange scares the living shite out of me. Particulary Craptsy. Fair enough and if your willing to take that risk Im sure you have many more coins but trusting 100k to some random guys, jheeze not for me.
Yes, you have a very good point, after nearly loosing 100 BTC worth of CYN on BTer recently & quite a bit on MintPal this has been much on my mind, I may well move towards just keeping a wall up on BFX and letting the markets arbitrage out any swings on other exchanges.
Thing is you can always transfer btc to an exchange if the price goes to where your buying anyway. The only time you may not have a chance is if somone was to dump a huge amount of coin. Im fairly sure that if someone wanted to dump that much coin in one go they would know your a buyer at around these prices and approach you to do an otc deal. You can still announce your buying points etc. Just such a large risk to take with little personal reward.
I'll still leave a large wall on BTX, but will announce price points where I will buy in large amounts if the price moves there or if anyone wants to sell direct to me, atm it's 0.012222 BTC/DRK & $3.00/DRK, with a guaranty not to go under 0.01111 BTC/DRK.
If I do remove the physical Cryptsy wall then that won't be until after 24 hours time so as to give good notice now and I'll make the BFX one larger when I do that as well.
I didn't move my funds off of BTer because moving CNY would be complicated I imagine, I guess that I could have done so by buying NXT but decided that if they allow that then hopefully soon they will permit DRK or BTC withdrawals which I'd prefer and it seems that the funds are safe, though I've lost a lot being in CNY while BTC rises, still swings and roundabouts.
