Very easy
For VPN you can use Mullvad. pay with XMR, no email needed.
For the node, download the official monero GUI wallet from Downloads
After install select "local node". It will take a couple of days to download the blockchain but after that you are good to go.
You will need a few hundred GB of disk space, at present my node is taking up 204GB.
Tails was discussed a few times already, it is indeed a great way putting up an extra security layer on your cyber privacy. I use tails on an USB device.
There is a great article which I learned from in mentor group gold
Before that I didn't knew about it. Even the article is old it is still valid and a amazing guide for setting it up.
The advantage of using Tails is that your computer can’t be traced, and if you set up at an internet café or a public library, you’re invisible online as long as you wear a hoodie and maybe even a fake beard. The transactions themselves, of course, can still be tracked and have nothing to do with Tails.
Is there also any additional advantage of using an OS like tails to not leave any traces? I do not know how much fingerprinting can impact the secrecy?
