Bitcoin sees unprecedented levels of buying with Bitcoin.Info showing a price surge of more than $3000 over the past 24 hours.

Today has been one for the record books as reports Bitcoin prices topping $18,000 and a market cap of over $300 billion. This newest milestone comes amid a flurry of significant all-time highs over the past 24 hours as Bitcoin climbed from $14,000 at this time yesterday to its current price of $18,053 at press time.

There is some speculation that news of the Lightning Network’s successful test yesterday, in which bitcoin was used to instantly purchase a cup of Starbucks coffee and a article, was at least partly responsible for the most recent flurry of buy activity and resulting price surge. While such small purchases seem insignificant, they mark a turning point in the race to solve Bitcoin’s scalability problems.

GDAX has really lead the charge with regards to western exchanges, as prices climbed to almost $20,000 before a large run of sell orders brought the price “crashing” back down to more normal levels.
