I want to use 1Broker but I won't lose any more of my BTC to theft. My BTC1.84915808 stolen in the Bitfloor hack (not including the partial pathetic repayment of BTC0.02055598) was the last time I ever let my own BTC sit in private keys I don't exclusively control. No matter what anyone's security claims are.
I don't have a problem when I am given OPM to work with, though (like Bithorse.co admin giveaways that have been the only deposits made to my account).
i understand how you feel, i lost a Pretty Penny when MtGox Screwed me.
However i feel Pretty Secure leaving money in 1broker, they keep "5-8%" hotwallet, "92-95%" Coldwallet.
that is what CoinBase/BTCe did and they have beeing doing fine so far.
let says if "HotWallet" did got Hacked. Losing 5-8% isnt a big deal. they can make it all back within
3-6 month or less, of Their profit.
what i do is i play with 5BTC, everytime i make 1BTC profit. making 1BTC profit is realistic because of x200 leverage you can use. i would withdraw the profit into coldstorage.
a way of reducing risk,
