The bitcoin pioneer, who was believed to own over $1 billion in the world’s No. 1 crypto, making him, at the time, one of the asset’s larger single-holders, died off the coast of Costa Rica.
According to a Spanish-language publication, Teletica.com, Popescu drowned at Playa Hermosa de Garabito, Puntarenas in Costa Rica.
Popescu was viewed as a pioneer in digital assets and one of the earliest adopters. An article in Bitcoin Magazine written by Pete Rizzo said that Popescu was known for starting MPEx, a bitcoin securities exchange, around the same time as the Coinbase Global launched. At its mid-April peak this year, Popescu’s bitcoin holdings would have been worth nearly $2 billion.
