HONG KONG: Bitcoin fell as much as 15 percent on Friday, extending its loss from its intraday high this month to more than 30 percent.

The digital currency dropped to as low as $13,048 before trading at $14,079.05 as of 12:07 p.m. in Hong Kong. Bitcoin, which peaked at $19,511, is still up more than 1,300 percent this year.

Investors are having a “reality check,” said Stephen Innes, head of trading for Asia Pacific at Oanda Corp. “At the heart of the matter was a frenzied demand for coins with limited supply has now led to unsophisticated investors holding the bag at the top.”

Bitcoin’s drop comes amid concern that an offshoot is becoming a stronger rival to the more well-known cryptocurrency. Bitcoin cash, which emerged earlier this year amid a split between factions over proposed software upgrades, was added to Coinbase Inc.’s offerings this week.

There are growing signs of mania for anything cryptocurrency related.
