I do agree most cryptocurrencies are scammy, or traded speculatively. It’s a free country, so one can do whatever they want to with their own money, but I personally think they’re like greedy gamblers.
I’m a Monero user, not a trader, not an investor. I have Monero because I use it. I support it because I’m a privacy advocate. I’ve never even once used a CEX, totally unrelated to investment. Your points may be valid for those investor people, though.
For those who are still on Win 7: Firefox (and so Tor Browser) will stop supporting Win 7 soon. Seriously, you better plan to migrate to Linux. Not-so-good privacy issues aside, everyone knows Windows is not very secure/safe/convenient anyway.
