How does this work? Sorry new to Bitcoin and trying to learn.
If u are concerned, and why not be, here is a quick method for safer, but fairly quick and easy, Bitcoin use.
1. Obtain bitcoins
U can use a legit platform, I prefer circle since no fees and ease of use, to buy the bitcoins u will ultimately use to pay for whatever. I personally do not think there is a need for ATM or similar in person methods to buy bitcoins. Let's call this Wallet 1.
2. Create a Tor wallet like Electrum for example. U can use whatever u want. Include no personal info when u set this up. It's just a blank wallet to send payment from. Let's call this Wallet 2.
3. Access a Bitcoin mixer/tumbler (simple google search will find several good ones)
It will ask for a 'forwarding address' on the main page. Put the Wallet 2 address here. Then select a fee % if u want. It's recommended to change this amt each time.
Then click on 'mix coins' or 'tumble coins' or whatever it is called on the tool u are using. The resulting page will provide u with a Bitcoin address. Send the bitcoins from Wallet 1 to the address they provide.
Once sent, the coins will be 'mixed' with a pool of others and ultimately removing the link to u and the coins u purchased. Once mixed they will be deposited into the forwarding address u provided in the beginning (aka Wallet 2).
Send payment from Wallet 2 to whoever.
There are additional steps u can add to increase security, but this is just a quick crash course in it.
