Popular ETFs of Blockchain List: Dividends

Blockchain is perhaps best-known as the technology that underpins cryptocurrencies like Bitcoin, Ether and competing altcoins.

Blockchain solved a problem as old as bartering itself: how to efficiently exchange assets. Letters of credit, paper money and minted coins have been around for centuries, but are cumbersome to trade and track. Innovations like credit cards and the internet improved speed and efficiency, but many transactions still go through intermediaries like credit card companies or banks. The system has its drawbacks: merchants are beholden to financial institutions that charge substantial fees, there can be significant lags when transferring funds, and large centralized financial networks are prime targets for fraud and cyberattacks. Moreover, not everyone has access to traditional banking and credit.
