What is the need to use Cloudflare's SSL, there are alternatives as letsencrypt...Good for a blog maybe but as a mixer CF is a NO, NO, NO as everything is unencrypted.
Cloudflare is able to know and collect visitors' IPs, what's inside the letter of guarantee, what's the deposit address, bla bla bla
Perfect to get the address source and the destination
Imagine an agency sending a request to CF, the person is busted...
Good things you noticed it, the privacy you could have is as good as using SPV wallet and connect to full node/server without VPN/Tor.
Is there any advantages that I am missing here, compared to Chipmixer, Samourai and Wasabi wallets?
Both Samourai and Wasabi wallet are more transparent and you have full control your Bitcoin all the time. I would use both over any kinds of mixer.
