Stock Stream is the worlds first cooperative multiplayer stock market game using real money.
The stream uses $50,000 real USD invested on a stock trading website which has no trading charges (Robinhood).
As of May 30th at 09:00 EST, viewers of the Twitch stream can comment in order to buy / sell shares in companies.
The game will run until the funds fall below $25,000 and there may be prizes in the future for top traders.
The Twitch channel is https://www.twitch.tv/stockstream for those of you who want to take part.
Good luck!
