There are two ways to move cash money to lightning on strike. One, as you mentioned, is to buy bitcoin. You canât send it directly to lightning though, as the bitcoin is held on chain. Therefore, you send it to your lightning nodes on chain wallet, and open a channel with it. If you donât have your own node, you need to start one for this option. If youâd like to send lightning bitcoin directly to a custodial service like WoS, youâll need to produce a lightning invoice within that service, and then scan it from the home page in strike using the QR code reader top right. Instead of âbuyingâ bitcoin, and then sending it, you simply pay the lightning invoice and strike will send your sats over lightning network to your other wallet service

If all your cash money is tied up in bitcoin previously purchased, and you want to move all or some of that bitcoin to one of the lightning wallets you control, simply sell your bitcoin within strike, and then generate an invoice equivalent to that amount, and pay it using the home page
