The verification is now needed only for buyers. That means you can sell your BTC on Bitmarket without going through verification prodecure, which requires you to have eBay/Allegro/Bitcoin-OTC profile, or sending ID scans.
Is it really online? Where can I find that verification process, because I just want to have a look at this process but there is no indication for something like that in my account profile.
You can find it under
Offers tab. There is a note in red font that tells you that you're unverified, and provides a link. But from what I see you already verified on Bitmarket with your eBay account. Maybe you just don't remember it.
What is the difference between "On Hold" and "Frozen"
My On Hold amount increased when I performwd a trade. What is going on?
You had your funds "frozen" because you wanted to withdraw them before I implemented the "on hold" mechanism. It was done so you can continue depositing, trading and withdrawing new bitcoins like before. Today I moved all frozen withdrawals to this "on hold" state, to be sure how much exactly Bitmarket owes to its users. From latest data it seems that the number is a bit smaller than I announced earlier, a bit under 19000 BTC.
