Last time i checked it's still gonna suffer from 51% attack? Or its ECDSA implementation might have NSA backdoor? There is no stats how many people were robbed

Last time i checked it's still gonna suffer from 51% attack? Or its ECDSA implementation might have NSA backdoor? There is no stats how many people were robbed, how many accounts where hijacked, how many keys were guessed (due to crap implementations) etc. I think there was no other technology in the world that lost so much of people's cash with no responsibility of any kind. Yeah, just like gold - if you lived in 860 AC and thought copper was gold too - then it's a valid comparison!
