all sorts of crypto is depositable, but not through the lightning network
if i want to send my bitcoin that i mine i would have to transfer it to coinbase (fee), or a lightning wallet (no fee), then transfer it to bovada (which is a fee with a lightning wallet)
lightning wallets at this point are widely used and have many apps that utilize them, allowing ways to deposit through lighting wallets would be useful and allow bovada to get higher deposits in general through crypto as i guarantee a fair share of BTC deposits bovada gets are through Source → Lightning wallet → BTC → Bovada
apps already utilize lightning wallets with low fees (like strike for example) so clearly itll be a profitable option for bovada
