Following from the $20 issue, this is a banknote-style celebration of cryptocurrency's milestone, the crossing of Bitcoin's $50,000 threshold - Featuring authentic banknote patterns, Bitcoin symbols, and Ada Lovelace - mythically recognised as one of the world's first computer programmers. The design reveals a weekly candlestick chart, plotting the journey to 50k. Only 8 editions of the 50k banknote will ever be made. Each edition is uniquely serial numbered.
