few beginner questions

[fire741]

Hi,
I started learning about carding a while ago and I think i'm ready to try it out within the next week or two. I just have a few questions before I do this to make sure I do it as safe as possible.
1. i wanted my main os to be qubes as it seems rather secure and quite useful for the carding method i would use, but since none of my laptops are able to run it, I thought of using ubuntu instead. running it like this:
ubuntu > vpn > mac spoof > VM (windows) > vpn > socks5
would that be secure enough?
2. can i use the same vpn acc for ubuntu and the VM or should i buy one for each
3. does anyone know a bitcoin or other crypto mixing site that isn't a scam
i'm guessing those crypto wallets with included mixers are a scam, so going to stay away from those.
any advise you may have would be much appreciated weather related to this or online carding in general.
thank you in advance
