I am not saying it is perfect. I am saying it is unlikely your wallet keys could be brute forced, which is what you are implying with your link.
I know the chance you get hacked is none zero. It’s the question of probabilities.
Could someone brute force or guess your pk? Yes. Is it likely? No. It’s very unlikely. In fact you are many times more likely to win a powerball than get your pk hacked.
Possibilities and probabilities are two different things and people tend to equate both.
There is a possibility that you could turn into a bathroom fixture tomorrow, based on how atoms in your body could rearrange themselves.
But the probability of that happening is very small. Now you could take this info and get paranoid about turning into a furniture (because well it is within the realm of possibility) or you can gauge the unlikely probability of this happening and live your life in peace.
I understand people’s desire for security could be a personal preference. To me 1/2^256 risk is worth bearing.
Banks have the same level of security as far as I know. They all use the same security technology.
But if you are not satisfied personally with that level, I completely understand. Then again you shouldn’t be using online banking if so.
One thing is to say I feel uncomfortable with the current level of security. The other thing is to claim the security is broken because some folks claimed to have found private keys to some wallets.
As others pointed out, they could have just created those wallets and published private keys. I highly doubt they found any of these keys as these wallets have peanut balances on them.
If the computational intensity to find a pk is the same for a wallet that holds millions of btc and .52btc, why choose the smaller balance one to prove your point?
Also why isn’t there any findings past 2017? A year has passed.
All these issues together make me highly skeptical about their claims. In my books they are a complete FUD.
