Yep, especially after the Game Stop stock debacle happened and drew a lot of people's attention toward Robinhood (or it could have been their massive advertising campaign and/or zero-fee trades).
But if I were a stock trader, there's no way in hell I'd use Robinhood after what they did, which was to capitulate to the government and freeze Game Stop stock trading. They're run by a bunch of amateurs and they don't even have a customer service telephone number. If you need to call them for whatever reason, you can forget about it.
How the hell does a listed NYSE company doesn't provide a customer service telephone number? This is ridiculous, how can customers accept this kind of behaviour? What you're describing seems more like the start of an anecdote rather than how a company really treats their customers ...
As far as crypto and Robinhood goes, I'd also look elsewhere for my needs--especially if I was looking to buy and hold and not actively trade. "Not your keys, not your coins" has already been referenced, and for a damn good reason. If you've got your coins in your own wallet, you aren't at the mercy of a 3rd party, no matter how trustworthy they seem to be. Things can change in a heartbeat, and why give up all that control over your crypto? Isn't that kind of the point of owning it in the first place?
The kind of thing that itches my soul is the fact that these exchanges - who already have a huge customer base due to their fee-less system when compared with "standard" financial institutions - are way faster in implementing (and accepting) BTC purchases than implementing a system for their users to withdrawn their recently bought crypto. I know that in the past they've said[1] that whenever a user buys crypto they go into the market and buy crypto in a 1:1 system, nothing really assures me that is happening. To me, as a suspicious person, the fact that I'm not even able to send my coins out of their system makes me believe that I'm just speculating on BTC price and nothing more. To see that they just care about money without understanding the concept of blockchain/crypto, just look at this answer regarding "Know your keys":
For people who preach “not your keys, not your coin”, we’re actively working on supporting deposits and withdrawals. As soon as that feature is available, you’ll be able to withdraw your crypto.
