Cryptocurrencies are inherently cryptic - it's right there in the name. And if you follow Warren Buffett's advice to never invest in businesses you can't understand, it may be hard to justify investing in a currency made of math instead of gold.

But it's also hard to ignore some cryptocurrencies' astounding performance : The price of one bitcoin jumped from just under $5,000 in March 2020 to over $60,000 as of this April.

The excitement surrounding digital currency may leave some investors feeling like the lonely kid at the pool party, wanting to join their friends having fun in the deep end, but too nervous to jump in.

For those investors who are cautiously curious, here are ways to gain exposure to cryptocurrency without buying it, and if you do decide to purchase, how to lower your risk.
