Ethereum is making a big comeback

Ethereum is making a big comeback. The cryptocurrency tumbled more than 15% to a low of $175.38 an ether in early action on Monday. It has since erased nearly all of those losses and is down 3.65% at $202.

Tuesday's slide below the $200 level was the first time the cryptocurrency was below that since the end of May/early June. Ethereum tumbled about 10% on Monday.

The cryptocurrency had gained close to 4,800% from the beginning of the year through June 14 thanks to a rise in popularity of so-called "Initial Coin Offerings" - a money-raising method that uses Ethereum's network. But, talk of a cryptocurrency bubble has put pressure on prices as of late.
