LONDON (Reuters) - Bitcoin's smaller rivals are eroding its share of the $2 trillion digital currency market. Of the dozens snapping at its heels, most have little use beyond financial trading - but few of the investors fuelling their rise seem bothered.
Among the major "altcoins" - as all cryptocurrencies aside from bitcoin are known - some such as ethereum aspire to be the backbone of a future financial system. Others, like Dogecoin, have no such ambitions, and are barely used in payments or business.
