Re: I want to upload all public bitcoin addresses on blockchain to mysql, How?
I know it will never work. But I l would like to see if I can build my own bitcoin collider.
I found a python script that generates a public and private key. I modified it to take an input file. I increment the 77 byte exponent by 1. Then put it in a loop. I check for a transaction history using a call to blockchain.info. If a transaction is found (i know, will not happen), I write the private and public key to a file. I update the input file at the end of each run.
I want to run it against my own database, instead of making calls to the blockchain.info. As you can see from my source, I put a 20 second between each call so as not to overwhelm the api. I also run the program with a sleep time between runs.
This is how I run the program from my linux command line.
while sleep 235; do python usethis.py; done;
Would love to get this running with no sleep time.
You need inputfile.txt example input

Re: working on a bitcoin collider program in python, Am I on the right track?
Here is the output if I find a private/public key combo.
I sent some bitcoin to the public address to see if it would work. I didn't actually find one in the wild.

working on a bitcoin collider program in python, Am I on the right track?
I modified a script I found to take an input file with a 64 byte hex integer (77 integer exponent). I check for any transactions and then increment by 1 and and check again. I put a 12 second delay between calls so I don't overload blockchain.info.

The world economy is intertwined, the US economy is dependent on the world economy and vice versa. Naturally the world economy would suffer greatly if the US economy failed, but it would eventually recover and other economies would fill the vacuum.
This was what I was gonna say. If Europe, China, or the US economy fail the effects will be felt worldwide. But things will recover. This is part of the issue today, Every region is messing with their currencies. Trying to force infinite economic growth every quarter.
Best way to predict the market is to force the market. When you want to buy, spread misinformation and fear. You can do this by using twitter. Or going to a popular forum and telling everyone your autistic brother has predicted a crash.
Re: Is it a waste of time mentioning Bitcoin to friends and family?
I don't talk about it with family. I do with my friends that like tech stuff too. I don't tell people to invest though, I don't tell people to invest in anything anymore, If the price goes down they will hate you.
I talk about bitcoin, Just as a small hobby for web and app development ideas.

Re: 0.5 BTC reward - smart enough to tell me what is wrong with this book cover?
The ants have too many segments.
That was my thinking too. Head, thorax, and Abdomen.
There are rumors of negative interest rate and cash confiscation in the US. I can see it happening.
Zero interest rates are what is supporting the stock market. Bitcoin is a good way to trade without going to banks and maybe hold onto your wealth.

Remember the Boy Scout motto "Be Prepared"? I believe in diversification. Yes, It is good to have some cash ready. But what about a run on banks? If you come walking out of the bank with your cash, there could be robbers or cops (civil forfeiture) following you home and ready to take your cash.
I am gonna do a garage sale. Post it in the local paper with "bitcoin accepted".
You guys gave me an idea too. Maybe make a youtube video of the garage sale and show how easy it is to accept payment.

Great idea. Ocean preservation sounds good. People love animals/dolphins too. I notice that on reddit. Feel good story about bitcoin people help ocean life might be picked up by reddit and quickly followed by news organizations.
I have a list of important passwords stored away in a safe for when I die. This includes my coinbase account. I will add my multibit password to the list too. Thanks for bringing this up.
Re: Bill & Melinda Gates Foundation funds Bitsoko, promotes BTC literacy in Kenya
That is pretty cool. I think Bill and Melinda Gates are really into making the world a better place. Opposed to the Bill Gates from Microsoft's early days.
This could help Africa become more technologically advanced. I view Bitcoin like NASA. It gets people interested in Technology and creativity takes off.
