READ MORE And amid this backdrop, there has been a further twist in the tale, with Reddit investors left angry at trading platform Robinhood. The app, first founded in 2013, is a stocks trading app that is predominantly used by millennials. But amid the Reddit-fuelled drive in the GameStop stock price, Robinhood announced they were limiting purchases of restricted stock. Robinhood co-founder Vladimir Tenev tweeted: "To be clear, this decision was not made on the direction of any market maker we route to or other market participants. Starting tomorrow, we plan to allow limited buys of these securities. We’ll continue to monitor the situation and make adjustments as needed."
