With trusted people, with legit dox exiting the forum for 10 +- BTC, this is not particularly good practice.
(1) The account could be hacked, sold or all the usual excuses could be brought into play.
(2) 500 BTC is a lot of money and easily enough to disappear forever, so the "you know where I live" argument isn't valid.
(3) Assuming this is just a bit of fun/a joke, for someone who I've seen with very good intentions on this forum [and for which I do give you credit], its really not a very well thought-out post. At the very least it will encourage other scammers who actually are corrupt to try this kind of thing and run with the funds. It will encourage thoughtless over the internet handing over of BTC, which is in most cases how people here get burnt.
1. Not likely. I'd say, extremely not likely. It's possible, yes, but I say the odds are almost negligible. I am biased, since I'm the one talking here. What could happen is I get hit by the proverbial bus, but then, that's a really bad situation for me I'd rather not be in.
2. 500 BTC, right now, is only 200,000.00 USD (two hundred thousand US dollars). I can't even buy a decent house with that money. Where would I go with that money? (With a small family of two toddlers.) It's not high enough for me. Actually, I dare say, no amount is high enough for me to even think of trying something. There are some things in this world that can't be bought with any amount of money, or bitcoins.
3. Yes, maybe, not a very well thought out post. I'm not encouraging scammers, and the only scammers who would be encouraged are other "Trusted" or "Hero" or "Legendary" members.
I'll let this thread die if no one responds. Go about your business. Nothing here. Just some bored bitcoiner.

No problem, just thought I'd point out especially number 3. We have enough cr*p in this community as it is, don't need to be attracting more scum..
