This. Consider showing respect for Nakamoto not by naming things after him but by using the name he gave to the currency he created: bitcoin.

These beauties are worth $0.0002 each. 1 year ago this was Venezuela's higher denomination bill.

This is both hilarious, scary and the perfect example of why we need Bitcoin. Venmo worried about the word "Cuban".

Just passed the #LNTrustChain Torch to @kallerosenbaum

Sent over $100 from South Africa to Sweden in seconds

The torch has passed through over 150 people in countries around the world. No banks were involved.

This is why I got into #Bitcoin ⚡⚡⚡

An old, but still relevant and true education meme about #Bitcoin. What it's describing is the difficulty of hash collisions.

All the mining hashrate in Bitcoin's entire history can only bruteforce a 90-bit hash. If there were two "Bitcoin"s, that'd be 91 bits (not 180 bits).
