Bitcoin is Stupid and Does Not Deserve an Emoji (blog post)

This is a most excellent place for technology news and articles.
No single wallet has even close to 1 million Bitcoins. It's a public block chain and you can find a list of the largest wallets in a website like this: https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html
Also, regarding the unfair advantage of the genesis block, Bitcoin's code was actually written in a way that prevents this balance from being transfered. It's forever locked in the wallet at this address: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa.
True, the Genesis Block is fixed, but it's speculated that Satoshi did most of the mining during Bitcoin's initial experiment. I have seen estimates online that the first 22k blocks were mined almost exclusively by Satoshi, all to different BTC addresses, 50 BTC each. Worth practically nothing back then but worth over 2.5M today. Every 10 minutes or so, Satoshi found another one.
