One golden rule I have learned ~10 years ago from Andreas M. Antonopoulos:
Any device, anything what has been ever connected to Internet at least for one minute - should be considered 100% UNSAFE. ANYTHING.
Damn scammers are everywhere: in you phone, TV, Media player, Tablet, PC, in you keyboard, in your washing machine, media player, vacuum cleaner, lawn mover, garage gate box, security cam, alarm night clock, wirelesses printer. Anywhere.
Once you start play crypto - YOU MUST LEARN how to deal with it.
So very important! Hear stories about people losing their crypto and usually for using a phone. So much careless possibilitiy fer new users wen they don't know enough. Love the mention of household appliances!
It is beyond imagination in knowing how connected we are.
Hence the smart lamp from Action market for 6,99 wants to connect to a cloud in China... It runs on a closed home network in my brother's home. Many other cheap smart devices are trying to connect to the same cloud in China...
