Correct, Jack Dorsey is one of the biggest proponents of Bitcoin so it's limited to BTC, but yes... that app has Bitcoin purchase and withdraw enabled after some KYC/AML checkpoints. It's been a unicorn within a unicorn [0] and has led to launch of Block, and what will be the production environmentally focused miners with a partnership with Blockstream and Tesla and the battery packs just landed last week [1].
The fees are higher than the aforementioned exchanges, but this is what is being built out, and I have now problem with that at all as an early adopter.
