Cryptocurrencies may have a market cap of $182 billion USD, and initial coin offerings (ICOs) may have surpassed venture capital as a means of raising early-stage money, but most Americans still have very little clue about either.

68.4% of Americans have never heard of Ethereum, Bitcoin's little brother, according to a LendEDU survey.

21% of Americans believe that investing in an ICO is illegal.

There is currently about $30 billion of Ethereum circulating, although the price fluctuates constantly. After massive gains in recent months, there is almost $110 billion of Bitcoin in circulation. Bitcoin is much better known: 78.6% of Americans have heard of Bitcoin.
