You shouldn't be using mixer sites, they gain complete access to your funds and your transaction history. Coinjoin enabled wallets like
Wasabi allow you to create
anonymous on chain transactions without giving anyone else the chance to steal your BTC.
I learned this afer placing the transaction. I already have it in place now. Glad I was testing it only and didn't send a larger amount.
The legit site is the one that end with .io
.cc will likely be a scam site but the link is not working, although the domain has been registered. Avoid all sites related like .cc, it is a scam site in my opinion.
It is working for me.
