Bitcoin and other cryptocurrencies can be among the most volatile securities trading today.
A safer way to invest in cryptos and blockchain-technology companies is through exchange traded funds.
The Amplify Transformational Data Sharing ETF BLOK is, by far, the largest ETF focused on cryptocurrencies and companies that use or develop blockchain technology. It has $1.3 billion in assets and is actively managed. The second-biggest ETF in the space is the Siren Nasdaq NexGen Economy ETF BLCN, which is passively managed — it follows an index — and has $291 million in assets. Both ETFs were established on Jan. 17, 2018.
