I can't tell you what every person uses it for. But I can say for certain that it is already being used to transfer money cross-border. And I can say for sure that people use it in nations like Venezuela, where the banking system has failed. How do I know this? I run a business which buys and sells digital items for online games. Every single seller from Venezuela is looking for BTC. Most sellers from Kosovo as well. And tons of people are asking for BTC in general. The majority of $500+ transactions in the industry (often B2B) are done in crypto.
