This is just a random person's opinion on the topic, but it's always good to hear different opinions from your own. I decided to read through the article and basically the guy concluded that Robinhood will likely the the BEST place to buy crypto from in the near future. His article just touched on some points for why it could hurt rookie traders that just use market orders and he questioned if they would be able to handle the influx of new users for crypto. He did fail to mention that it is only rolling out in 5 states to begin with so there wont be nearly as high of a number of signups as it says on the waitlist page until it is rolled out to more states in the US.
