I agree. I was just pointing out that important condition so people are aware of the risk. Again, if you put your coins there, they can be held hostage for whatever "proof of identification" they deem necessary, at any time, with no notice, regardless of amount. The 2000 USD, etc. thresholds specify the minimum amount of documentation they require, not the maximum.
My take on this is that I have zero interest in giving my identity documents to any of the current crypto exchanges or other crypto businesses, and I have never done so, nor do I plan to. Not because I have anything to hide (all of my activities are entirely legal, and my identity isn't even that secret anyway), but because I simply don't trust them to safeguard it. Look at how many have been hacked, have had data breaches, rogue employees, etc. If I put coins there I'm aware I may have to forfeit them, so I act accordingly, mostly by exposure limits. Which is needed anyway given the risk of being hacked or "hacked".
You're right to point it out, I guess I assumed most here would know that any exchange is a risk (of many kinds).
I just feel Polo is a good one, and (granted, perhaps emotionally swayed) wanted to step up for a little balance in case it got a total kicking.
