In this case when you create a Bitcoin address with a character series(6789012345678901友達彼女雪男),(Llisp),(1234542152695) of any length, a collision occurs. Let's consider Bitcoin (tt) as a cold address, in this case someone else can create the cold address. Such logic, much amaze, wow. So you're saying if I have the target of decimal 10 in binary, 00001010, I could find a collision just by finding A in hexadecimal ?

OP, again, BITCOIN ADDRESSES ARE NOT COMPOSED OF RANDOM CHARACTERS. In fact, there is actually no such thing as a Bitcoin address. On a technical level, there is no such thing as a Bitcoin address. Rather it is a way to represent a 160 bit number, the RIPEMD160 of the SHA256 of a public key. An address is simply an encoding, a way to package the hash of a public key in a manner which allows for some basic error checking and a way to shorten the number of characters that people have to deal with.
It doesn't matter how many or what characters are used for Bitcoin addresses. Increasing the characters used will simply make addresses shorter, they will not remain a fixed length because they must convert back to a 20 byte number. That is what stays constant, not the length nor the character space.
Let's try a picture for OP.... I'm guessing he's using random alpha characters to generate a bitcoin address and there by searching the internet with his results to product a "hit" on a collision. Levent: This is how bitcoin addresses are generated:

It's part of a series of similar diagrams. I don't know where to find them now, but they were made by etotheipi I think?

On a technical level or not,
I believe Bitcoins greatest vulnerability stands with people who don't understand what the ***CRYPTO***-currency actually is and with the people who come here to make a quick penny.

There's a better challenge open, too: there's over $10 billion worth of Bitcoins secured by "easy-to-collide" private keys. Simply collide a few of the bigger ones and take the money! The fact that this hasn't happened should be proof enough that OP's system (whatever it is; I can't understand what he is trying to say) doesn't work.

Imagine me a newbie reading it from top to bottom. That is a lot of stress and ending up it cant be done. You are saying you guessed some account of a Russian by a mere coincidence? There is a 1/a billion chance I think for this to happen? And you are saying our bitcoin is hackable after how many years of service? Oh crap! My head hurts after reading. Need some rest.

OP, you are completely and absolutely wrong. The private keys ARE NOT randomly generated characters. They are actually 256 bit numbers. This means that the total number of possible private keys is 2^256 - 1, which is a ridiculously large amount of possible private keys. Those private keys are converted into the characters that you see through a process known as Base58 Check Encoding ( https://en.bitcoin.it/wiki/Base58Check_encoding). You cannot just throw random characters together to get a private key because it will probably fail the Check part of Base58 Check Encoding. The Check is the first four bytes of a SHA256 checksum of the private key. Note that most Bitcoins are spendable by addresses, not public keys. Addresses are only 160 bits, and any private key whose public key hashes to the same 160 bit address is able to spend the coins at that address. So for most coins it's "only" a 160 bit search to find a private key that can spend them. You don't need to find the same private key as the proper owner of the coins, you only need to find one which gives the same address. Of course, a 160 bit search is still impractical to carry out. But it's a lot easier than a 256 bit search. and in this case: Bitcoin (cold address)-> person can coincidentally create an exact same account number (cold address) . If someone uses something non-random, sure. E.g. "Dog" as a "brain wallet" or a non random PRNG. Otherwise, no. Saying otherwise is either FUD or not understanding math etc as Foxpup etc has explained. I know it's an old topic, but I think I understood what the OP wanted to say. The answer I quoted sums it up, in my opinion. I got here while searching google for the PUBLIC key I created... using the phrase: 12345678901234567890 (brain wallet) This phrase make a private and public key that apparently have been used for real before. Private key: 5Jf6mGTeCg37iZST1ukHXacwyuhjL3ABvEcpgwCRQX9y9fLGLbD (thats the same key the OP found/created) Public key> 15eUHuCMKGekXmfH2B5awPWnwY3qVe3Nz1 used this site to create the keys: https://walletgenerator.net/What he means, I belive, is: What stops someone to start gessing several keys.. and looking for it in block chain. When you find one that has money, transfer it. places that I found this key: https://bitcointalk.org/index.php?topic=156609.450https://blockchain.info/address/15eUHuCMKGekXmfH2B5awPWnwY3qVe3Nz1Im a total noob as well... and im starting to learn (a little bi late, i suppose) about this incredible world. Thanks!

If bitcoin and all cryptocurrencies are this vulnerable, then it should be a simple enough task to prove it to us all by hacking the blockchains and bringing the entire market crashing down to a grinding halt. If, on the other hand, you have no idea of the actual numbers involved and are just saying generally that in an infinite time and universe, anything's possible, you are correct. It still isn't bringing aliens to my doorstep, nor is it making it any easier to hack the blockchain with anything less than a few billion years of computing time. And really, once we have that, aren't we better off trying to hack the Ultimate Answer to Life, the Universe and Everything? Granted, we'll probably discover it's 42, but still.

Public key> 15eUHuCMKGekXmfH2B5awPWnwY3qVe3Nz1 Yeah I think you got it right. This basically just means that it is insecure to use bad randomness to generate your Keys. But that's an obvious thing and does not only apply to Bitcoin but to crypto in general.
