Because of that I can just recommend anybody to use a dedicated device or hardware wallet for cryptocurrencies - do not expose your funds to thiefs and scammers. I wish I had taken these precautions myself in time.
I use (multiple) hardware wallets.. or I would have lost everything.
I also use a dedicate PC to do my crypto stuff.
I'm also not 100% noob concerning the computers/IT stuff.
And considered all the above, howsoever, I still get robbed of something.
Analyzing the situation AFTER it happened, it's easy. There's like ten things that I could have done differently to avoid it (of course!), but the point is that a life is long a life... and sometime you can't be perfect every single day, otherwise we will live in the paranoid and fear.
- I should have paid much more attention to the wallet used, opinions on Reddit, guide on the web, an apparent legit website weren't enough.
- The fact that no AV/scans found anything wasn't sufficient to call the file safe.
- I could have used a VM to do this stuff (I have like 5 VM's installed on my machines, that are only a click away);
- I could have paid much more attention to how to use my trading platforms (leaving it open while not being at the PC is stupid if looked after..);
- And finally the luck (unluck): my daily hours (and dinner time) are normally different, that day I got delayed by other stuff, in 99% of others cases I would have been at the PC soon enough to block it before;
It's all about "imperfections" concatenate with each other and I consider myself very lucky to have adopted hardware wallets from the very begging and using 2FA on every exchanges, so while I learned a lesson for "cheap" (cheap if compared with your amount) I won't consider myself "completely stupid", I'm not perfect as every other human, maybe for the next months.. years.. I will pay much more attention than usual, but i'm sure that one I eventually forget to be extremely paranoid and I may do the same mistakes again.
My idea is: don't be a complete bloke (in example: don't leave your wallet full of money on a bench in a mall), but neither don't start to be paranoid (don't hide your money in a cave, under a rock, protected by lions), because if you start to be extremely paranoid you won't live anymore. so where you hide your hardware wallet seed? What if someone will find it? Did you split in 4 parts sending it 3 places around the world? do you remember all the 24 words by memory? What if your memory will not be good anymore? And stuff like this... you will always live with an "acceptable risk".
