Read More9/ I happened to see the word 'coinbase' in the Bitcoin Wiki (link: https://en.bitcoin.it/wiki/Coinbase) en.bitcoin.it/wiki/Coinbase (it is a part of the Bitcoin protocol) and liked it. I purchased the domain (link: http://coinbase.com) coinbase.com a few days later for ~$1,800. Millions of customers later here we are.
