Dogecoin was soaring again on Wednesday morning, surging 20% as the cryptocurrency continued to benefit from speculative trading.

The digital coin based on a Shiba Inu meme last traded at just under 68 cents, up about 20% for the day. It broke above 50 cents per share for the first time on Tuesday.
