but people that are very rich in bitcoin or other crypto should be concerned about privacy. Nobody can be 100% private, but they may prefer to have privacy in one area or the other.
I agree, in such cases, privacy is simply necessary. If I had 10,000 bitcoins, then I would also treat my privacy very differently than now.
But other browsers also need to be configured before initial use, and not use the default settings.
Not certainly in that way. When I launch Opera, its settings are just to improve the experience. When I start TOR, I need to change the IP, because it does not work with Russian IP, I need to set up bridges so that it starts and for full privacy I also have to play around with the settings. Do not compare the settings of everyday browsers and TOR, they are completely different settings.
Why Opera and not another browser? For example, Firefox.
Because it is convenient, unlike the same TOR, which is terribly inconvenient for everyday use.
or have you chosen what is convenient and familiar to you without giving a damn about privacy?
I wonder how? It reminds me of horror stories about the disregard for their security, which is expressed in the use of CEX. I've been using Opera for over 10 years now, and you know, I didn't feel at all that my privacy was seriously affected by it. You can look under the microscope at some differences from using Opera and TOR, but they are so insignificant for ordinary users that calling it such big words as SPIT ON YOUR PRIVACY is at least ridiculous.
