Any wallets are only as safe as you are. I would usually recommend keeping coins offline...

Hi, I downloaded GeoCaching.
Do I need to use filter? if yes, Do I need to use Geocaching premium 29.99/year?
Thanks

Acabo de entrar en el mundo de la cryptomoneda y envié toda mi producción a Coinbase. Luego entro en mi wallet y no veo dinero, y de paso me sale un mensaje que dice que no puedo comprar ni vender por restricciones de mi país (Venezuela). ¿Significa eso que perdí mi dinero?

Public and private keys do not even have to be the same to generate the same bitcoin address.

There are 2^256 private keys, that create 2^256 public keys. BUT there are only 2^160 possible bitcoin addresses. So on average there are 2^96 (=79228162514264337593543950336) private keys that generate the SAME address.

If (and when) an address collision will happen, then it is much more likely that it will happen with different public&private key pairs than it being with two exactly same keys.

I might be wrong but are you referring to bitcoin wallet or wallets in general? I do believe there is a possibility of multiple address but as of now, it is still highly unlikely. I would love to know know the developers would tackle this problem though.

Because you would have to check if the address already existed, contains a balance etc.

You would need a lot of time and a lot of computers to brute force it like that.

I saw people in our "research group"  playing with raspberry and arduinos but don't know if arduino has computacional power enough to make a hash.

Frontend is up, stratum is still down. I'll relaunch a new stratum soon

Thank You!
