Last July an unidentified man held up a “Buy Bitcoin” sign during Janet Yellen’s testimony to Congress. Since that call, Bitcoin is up over 250%.

The unidentified man was rewarded by the bitcoin community by netting $15,000 worth of donations and was declared Coindesk’s most influential in blockchain in 2017.

Like it or not the Bitcoin sign guy was a major influence in 2017, as he seized the spotlight and promoted a decentralized cryptocurrency from the most powerful central banker in the world.

Well done.
