During last season, Spencer Dinwiddie signed a three-year $34.4 million extension to stay in Brooklyn.

Recently, Dinwiddie announced plans to turn his contract into a “digital investment vehicle” where investors would buy digital tokens, backed by his contract. Dinwiddie would have more money upfront to invest, investors would make some money off interest, and if he opts out of the final year of his contract and signs for more than the $12.3 million he is owed, his investors will make more, too. If you want more details, here is a good explanation of his plans.
