This is how any market works! You need to take advantage of Robin Hood glitch or you lose.great time to be alive. Fiat banking has glitches. I hope these people stay away from btc or otherwise their "programming" skills could have even worse outcomes.
Sadly bitcoin is already on the Robin Hood app but only as an asset with no link to any real BTC you could withdraw so its only "investing" sadly.
If you ever wanted to generate passive income you need to leverage your investments to the maximum of your margin or you will never be able to afford your dreams.
