Bitcoin is getting use case from all around the world. Some are offering the POS systems and some are offering the vaults. And some are offering it as a features of banks. Now comes the spending part. Often the places accept the crypto and they do have prices listed in the dollars. And some of the time they don't have the stablecoin acceptance there. 

Lava vault wishes to address this as it allows spending in fiat and internally deducting the bitcoin of that price at the same time. And they offer the vault system to lock your bitcoin for holding and spending purpose. 

They are now slowly growing. And on the Nostr network there seems to be many users which are making use of the Lava. And that means they are in the work for the use case as well. In short a lot of bitcoin use case are coming around. In grand scheme of things we can see how the Lava vault would be making some good returns for anyone who wants to hold and spend in places where you can do the same. 

Borrowing feature is also there. And there are also option to send funds overseas. As it is bitcoin you don't need to know and won't know where the destination address is going to withdraw. So it'd be worth exploring the Nostr, lightning network and the shops where the Lava can be spent.
