industry as in?

in person I've witnessed countless Bitcoin transactions for goods and services. books, video games, food, tips, cash, taxi fairs, you name it, there has been a Bitcoin transaction for it.

nowadays these in person transactions are quickest over Bitcoin's lightning network, as it's pretty much instant and free(very small fees). But people still use Bitcoin's base layer to do the same kinds of transactions, they can take longer though (10 minutes on avg with a high fee).
