Investing social network eToro has launched Crypto-currency "CopyFund", providing a way to invest in Bitcoin and Ethereum online.

The CopyFunds invest in the two largest cryptocurrencies: bitcoin and Ethereum. Their weighting will be determined by the market cap of each cryptocurrency. The minimum investment is US$5,000.

The company said that the launch owes to the growing market cap of cryptocurrencies, which recently hit US$100bn.

Due to a ruling by the New York Stock Exchange, bitcoin ETFs are barred from trading. But its still possible for funds to invest in crytocurrencies.
