Bitcoin raced past $14,800 on Wednesday, just a day after it went over $12,000.

The cryptocurrency’s market cap is now $247 billion, which place the company slightly ahead of Visa’s current market cap of $242 billion.

Bitcoin has now surged by more than 40% this month alone.

The growth has been stunning for some and terrifying for many others. Many bank CEO’s have blasted Bitcoin as fraud, calling it a Ponzi scheme.

Bitcoin started the year at around $960, giving it a market cap of nearly $15.5 billion. It is now very close to going past $15,000, a 15-fold increase in under 12 months.
