Anybody considering purchasing any digital assets off of crypto::stocks needs to be made aware:
DVC, LTC, and BTC wallets are supposedly offline (preventing one from withdrawing) even though it seems to be accepting dividend payments from asset owners for shares held any attempt to withdraw your coins will currently fail.
I don't like CryptoStocks at all, but the two things you've mentioned are completely disparate and can run in isolation. In order to accept dividend payments all it needs to do is run a node and watch the blockchain ("watch only" style). To withdraw funds, though, that's a hot wallet and would normally be on separate infrastructure if they have any semblance of a clue.
