As usual, you guys are very informative. Thanks to all.

larry_vw_1955: I'm not really worried about the tax collectors. One of the (very few) good things about living in a lawless country is you don't really have any obligation to pay taxes, and nobody can do anything to you if you don't. The downside is you have to fend for yourself, because the police is just as non-existent as the tax agency.
The reason I'm worried about security is twofold: first, Argentinian hackers are said to be among the best (not surprisingly, considering Argentinians generally have penchant for doing damage), and second, if you do get hurt (physically or financially or whatever), nobody protects you, you're screwed. The law here is so twisted that if you defend yourself,
you go to prison.
ETFbitcoin: I'm setting up to use Binance. Might I have any problems if I use my wallet (I'm intending to use Tails on a pendrive with persistent storage and Coinomi) through Tor with them?
And yes, I am using 2FA authentication.
n0nce: yeah, I'm already setting Tails up, and I intend to never connect it to the internet. I am loving your steel idea though. Stainless steel. that would be one helluva way to store your seeds.

Typically, if "something" costs USD 50 in the US, it costs about USD 300 to 400 here. To give you an idea, a few years ago I bought a gun. Made in Argentina. I could literally take a bus and be at the factory's doors in less than 40 minutes. That gun doesn't exist in the US, but a similar one (same brand) is about $300. I paid $850 for mine, on sale.
Pmalek: yeah, I'm already doing all that. just thought it'd be nice to add an extra layer of security, just in case. in the (hopefully near) future I intend to have a dedicated computer for trading, and connect exclusively through Ethernet, but for now I have to use public wi-fi at a Starbucks store, so I'm getting very paranoid on that, especially since Starbucks has already had some "issues" with their network getting hacked in the past.
Charles-Tim: so, no Tor and no VPN. Got it. Thank you.
BlackHatCoiner: that's way over my head already. Guess I have some serious reading to do...
Again, thank you all for the replies.
