Ordinary investors are at an even greater disadvantage in smaller digital currencies and tokens. Among the coins people invest in, bitcoin has the least concentrated ownership, says Spencer Bogart, managing director and head of research at Blockchain Capital. The top 100 bitcoin addresses control 17.3 percent of all the issued currency, according to Alex Sunnarborg, co-founder of crypto hedge fund Tetras Capital. With ether, a rival to bitcoin, the top 100 addresses control 40 percent of the supply, and with coins such as Gnosis, Qtum, and Storj, top holders control more than 90 percent. Many large owners are part of the teams running these projects.
