Three addresses, all reaching the same market. Which one you take does not matter, but where you take it from does.
BlackOps publishes several onion addresses at once and all of them open the same market. Same account, same balance, same open orders behind each one. If a link is slow or refuses to load, you take the next and carry on, and nothing about your account notices the change.
A hidden service takes floods. If a market runs on a single address, an attack on that address closes the market for everybody until it passes. Publishing several means an attack has to hold all of them at once to have the same effect, which is a much harder job. The redundancy is not a convenience feature, it is the thing that keeps the market usable on a bad day.
A v3 onion is fifty six characters of deliberate noise. Typing one by hand is how people end up a single character off, on an address somebody registered specifically to catch that mistake. Use the copy button, paste it into Tor Browser, and leave it at that.
When the login screen loads, read the onion printed on the page and compare it against what your browser shows in the address bar. BlackOps prints its address inside the anti-phishing image and again in the header. A cloned page can copy every pixel of the design, because the design is served to anybody who asks for it. What it cannot do is show the real address while living at a different one.
If the two do not match, close the tab. Do not sign in and hope, and do not assume you misread it.
The moment that costs people money is not the outage, it is the search that follows it. Somebody finds their usual address quiet, looks for a replacement, and takes whatever a search result offers. Keeping a verified source saved means that moment never arrives, because the alternative is already in front of you.

Open these in Tor Browser only, and compare the onion printed on the login screen against your address bar. If they do not match, close the tab.
The missing Bitcoin option is the point rather than a limitation, and the reason is what a public ledger keeps.
From installing Tor Browser to a login screen you have actually verified. Four steps, and only one of them gets skipped.
A single coin market with multisig escrow and several live addresses, running since 2024.
Three routes, and the only real decision is how much identity you attach on the way in.
