Re: Bitcoin address mass balance checker [Tutorial and code]

I wonder why don't you run your own Insight server, rather than looking for other's Insight server?

For the record, I should say that one politically correct answer is that you first need to install a bitcoin full node, let it download the complete blockchain, and on top on that add an Insight server (https://insight.bitpay.com/) that you can query fast via API, and write and execute a script for it.

Now, I assume that most people are lazy and not willing to pull that off, or simply lack the technical skills required, so let me demonstrate my quick and dirty work-around that requires no installation or downloads. You just need a Linux machine.

Oops, i missed that. But personally i disagree with "politically correct answer", since IMO it's about ethical and if you can't setup your own full node + API services, you still could use public Bitcoin explorer rather than private Bitcoin explorer with sloppy security.

As discussed above, if using the script in the OP, you are most likely searching for thousands (or more likely millions/billions) of addresses, and a public block explorer is going to rate limit your searches.
