What can you do with Crypto on Venmo?

Could you elaborate on the potential uses of cryptocurrency on Venmo? I'm curious to know if it's just for payments or if there are other functionalities. For instance, can users invest in crypto assets directly through Venmo? Are there any unique features or incentives for using crypto on this platform? I'd also like to understand if there are any limitations or restrictions in terms of which cryptocurrencies are supported and the transaction limits. Finally, how secure is the crypto functionality on Venmo, and what measures are taken to protect users' funds?
