Dogecoin may have started as a joke, but one of its holders is sitting on some serious dough.

A single cryptocurrency account contains about $2 billion worth of the meme-inspired coin whose price has been pumped up by celebrities such as Elon Musk, Snoop Dogg and Gene Simmons.

The account holds about 36.8 billion dogecoins — a massive stash that accounts for more than 28 percent of all the coins currently in circulation, according to cryptocurrency data website Bitinfocharts.
