> Why is this an issue? Most websites support HTTPS.

Tor Browser and TAILS try not to keep any trace of the websites you've visited.

That means no 'frequently visited sites' start page, no bookmarks, no address bar autocomplete from history, and no HSTS unless it's preloaded.

So if a tor user visits bitcoin-mixer.com there's a good chance they'll be typing the address in manually - and a good chance they'll omit the https:// at the start.

(Also, a great many bitcoin mixers, for some inexplicable reason, don't get themselves HSTS preloaded)
