Whats the use cases for normal users?
I'm a normal user. I'm even going to pay taxes on my BTC gains (not worth risking jail time). I use Shared Coin so that everyone I send BTC to doesn't know my total balance.
That's perfectly fine. In fact i do the same, with an exchange with low confirmations. No one can guess my other addresses that way. So why do you pay these high fees to get back coins coming form scams maybe?
Shared Coin doesn't have any fees besides the miner's fee. But it's been down again for almost a week now and support says there is no ETA on fixing it.
Is there an exchange that is ideal for this?
Oh, i didn't realize it's not a mixer.
I use bitfinex. They only have 2 or 3 confirmations or so. But i don't remember if they need a verification. You can use poloniex too, they don't need a verification. But when you create an account, upload coins and instantly withdraw, then the system will hold your coins. Try to buy some coins, then cancel the order and when admin asks you then claim poloniex wasn't fast enough so you bought elsewhere. I'm not sure if it works the second time without problems.
But there are ways even without verification. Though you don't sound like you do illegal things so verification is no problem.
