Almost every one I meet has heard of Bitcoin. Mostly they believe that it's a scam (because there are a lot of those) or the first thing that comes to mind is trading and investing. As soon as I explain that it can't be seized or frozen and can be sent borderless and permissionless without banks and low fees - they get the use case. In general knowledge is very low. Many people are using Trust wallet (Erc) or Blockchain.com. Lightning is very new to most.
