At the same time, shares of the world's second-largest cryptocurrency, Ethereum (CRYPTO: ETH), traded roughly 2.7% down and shares of the meme token Dogecoin (CRYPTO: DOGE) traded more than 5% lower. In May, the CPI rose 8.6% on a year-over-year basis, which came in higher than economists had been projecting and made the market question whether inflation had peaked. I also really like Ethereum, given how much the smart-contract technology is resonating and being used in different industries.
