Yes probably a good idea to switch or update.
All I know is when I make a account on a few different games or try and use a email that someone already has I get
"The username/email address is already in use"

Why not add that to the code?

I am not comfortable with "chances for address collusion is near zero" I want a system that address collusion is 0. I don`t think it would be to hard to cook up.

Also what stops someone from multi boxxing brute force (to run trillions of them at once on a single computer), Having the bruteforce program attached to a blockchain so all the brute forces know what the other one has already tried, and getting private keys in the near future? I really think they need to add fingerprint/eyescans/dna captcha`s to secure wallets.  That way someone actually needs your eyes to open your wallet.

Like this poopy example: https://www.youtube.com/watch?v=l4x0vOAu0lQ Proof of Person/Population, blockPOP
(we could also make them take there fingerprint from the left, or right or upside down (fingerprint captcha, kind of like the eye captcha in this video)
If we went as far as DNA, we could actually tell the person is dead on the blockchain and someone is using dna/spit/blood/piss or carbon imprint, Proof of Alive.

Pretty easy to spread malware keyloggers on most phones or even on the apple app store or google play store, take a look at this kid for example.
Skip like 5 mins in https://www.youtube.com/watch?v=zcUDFnTj4jI Showing how your iPHONE can SPY on you (Apple Store) ScreenTime, He literally could make a bunch of apps that are just keystroke/video and screen loggers.

I used to work for AT@T call center, I had 0 security clearance, I could jack anyone's pin or sin cards. Once I hooked up a guy with 500 phone accounts because he was trying to make his girlfriend win in a beauty contest, my manager told me so long as he has the sin cards to make the accounts for him. (phone verification is not the way to go)

What if I go into a public library or school and keylog those networks or take over the mcdonalds wifi.

Anyways, everything you do on apple or windows is keylogged anyways.

I mean I rather have myself as my key, rather than a password written down somewhere. I know a lot of people will think this is some "mark of the beast" stuff but when they start getting blockBRUTEFORCED they will use it.
actually you just need a database not even blockchain to do this.
