i have $22k in Robinhood as "play money" to trade and learn. i lost $400 on AMD calls. WSB said the first time is free but i didn't win at the Casino. after my first failed calls, i just buy and sell stock. i bought 600ish HP stocks when it was low and sell it too soon when HP stock went up. overall, Robinhood have the best UI compare to tdameritrade and it isn't too bad if you just do normal trade and not options. one thing that Robinhood did that disrupt the retail trade is their no fee. tdameritrade used to charge $7 to buy/sell stock.
