The London Stock Exchange (LSE) has begun trading Bitcoin (BTC) and Ethereum (ETH) exchange-traded notes (ETNs), potentially paving the way for the United Kingdom to become Europe’s crypto hub, based on Alex Pollak, the head of UK for 21 shares. Based on the latest Yahoo Finance report, the ETNs are traded and settled just like regular shares, but they track the price performance of the underlying assets, in this case, BTC and ETH.
