    Bitcoin tumbles as rivals gain

    Bitcoin plunged as the cancellation of a technology upgrade prompted some users to switch out of the cryptocurrency, spooking speculators who had profited from a more than 800% surge this year.

    The cryptocurrency has dropped 9.5% since late Friday, extending its slide from last week’s record to as much as 29%, according to data compiled by Coinmarketcap.com and Bloomberg. Bitcoin cash, a rival that split from the original bitcoin in August, has jumped nearly 40% since Friday.

    Bitcoin cash is gaining popularity because of its larger block size, a characteristic that makes transactions cheaper and faster than the original. When a faction of the cryptocurrency community cancelled plans to increase bitcoin’s block size on Wednesday — a move that would have created another offshoot — some supporters of bigger blocks rallied around bitcoin cash.

    Supporters of bitcoin’s technology upgrade are now switching support to bitcoin cash There’s a panic about what’s happening. People shouldn’t panic

    The resulting volatility has been extreme even by bitcoin’s wild standards and comes amid growing interest in cryptocurrencies among regulators, banks and fund managers. While sceptics have called bitcoin’s rapid advance a bubble, it has become too big for many on Wall Street to ignore. Even after shrinking by as much as US$38bn since Wednesday, bitcoin boasts a market value of $101bn.

    Supporters of bitcoin’s technology upgrade “are now switching support to bitcoin cash”, said Mike Kayamori, head of Tokyo-based Quoine, the world’s second most active bitcoin exchange over the past day. “There’s a panic about what’s happening. People shouldn’t panic. Just hold on to both coins until we see how it plays out.”

    Bitcoin’s slump dragged down shares of cryptocurrency-related companies, including Hong Kong-based PC Partner Group, maker of graphics cards that can be used in the mining of digital coins. But there were few signs of wider ripple effects. Asian stocks were mixed as investors awaited continuing talks on tax legislation in the US this week.

    No upgrade

    The cancellation of last week’s bitcoin upgrade has left users to choose between the two versions of the cryptocurrency. On one side is the original bitcoin, powered by so-called SegWit technology, which aims to improve its performance by moving unessential data off of its underlying blockchain. On the other side is bitcoin cash, which allows its blockchain to handle eight times as much data as the original.

    Proponents of bitcoin cash believe their approach is simpler and closer to the original goal of bitcoin, which was described primarily as a payment system in its white paper. Supporters of the original bitcoin say that vision is too limited, and that by improving the blockchain with SegWit technology, bitcoin can become a new digital asset class that not only supports payments but countless other functions.

    While bitcoin cash has been around for months, it saw limited support as the community awaited last week’s technology upgrade for the original bitcoin

    While bitcoin cash has been around for months, it saw limited support as the community awaited last week’s technology upgrade for the original bitcoin, which promised similar features. Now that the upgrade has been called off, businesses that use the cryptocurrency primarily as a payment method are expected to increase adoption of bitcoin cash.

    While bitcoin cash surged over the weekend, it hasn’t been a straight line up. The cryptocurrency was trading at $1 325 at 11.53am in Hong Kong, down from a high of about $2 478 on Sunday, Coinmarketcap.com prices show.

    Bitcoin has been similarly volatile; it initially rose after news that it would avoid another split, but the gains were short-lived. It’s now trading at $5 948 after touching a record $7 882 on Wednesday. — Reported by Justina Lee and Yuji Nakamura
