LONDON — Cryptocurrency bitcoin cash has been rallying strongly over the last week and is up another 17% on Monday. Bitcoin cash, which was spun-off from bitcoin last August, has risen over 80% against the dollar over the last seven days and it up 17% at 11.43 a.m. GMT (6.43 a.m. ET): The rally appears to be driven by an upcoming bitcoin cash fork — industry speak for another currency being spun out of the underlying code that runs a cryptocurrency.

The fork aims to increase the processing power of bitcoin cash by increasing the size of the blocks of transactions that are processed. Mati Greenspan, an analyst with trading platform eToro, said in an email on Monday: “Bitcoin cash is moving towards a hard-fork on May 15th.

The planned fork that will increase the maximum block size from 8 MB to 32 MB and will also remove the SegWit protocol. “However, those looking to get a new coin or “dividend” out of this fork may be disappointed.

If all goes smoothly, the new coin that is created from the fork will completely replace the old coin. Though there may be some who try to keep the old BCH alive, they will very likely be the minority.

That said, there will be no free lunch, and no chain split unless things go terribly wrong. “Still, many crypto traders have the last few bitcoin forks permanently etched in their minds and associate hard forks with rising price and so the momentum is snowballing at the moment, especially in markets such as Japan and South Korea.” Read more from businessinsider.com…
