If bitcoin reaches the same market cap as gold, a single coin will cost around £420,069 - it's meant to be!

My half arse working out:

When bitcoin reached 1 trillion dollars a bitcoin cost around £37,124. gold's market cap is currently at 11.3 trillion dollars. So => (37,124 X 11.3) ≈ 420,069

Therefore I see this as our next checkpoint.
