Who is out 20 btc?
Side question - I have heard that 2fa coin buyers still were provided an address for the coin - I have heard they did not - which is correct?
20btc? Just another number/total dreamed up.
As for the side question - Both are true.
Look at post #185

In the beginning, it was some internal generated number. So, you didn't actually know the address from the coin itself; however, emails sent after the purchase included the serial number, coin identifier, and the public address. You would have had to check the website or had the coin graded in which they would put the pub address first bits on the slab details.
Later, the code on the coin was actually the first bits.
well then either way - there was at one point an address associated so the buyer could see that the coin was funded and for those that hold them now (if they have the address) can verify they are still funded or if they have been swept.
and that goes back to Todamont buying a coin that he did not even validate whether the address for the coin was still funded or not.
Todamont - which version of 2fa did you have? If you had to look it up on the site, I am assuming the first one - but then did you get the address from the seller?
Why would you not have verified the coin is loaded - stating because it had a COA is no reason not to verify whether coin is loaded.
