The major benefit is of course the huge upside to where the price could go. We've only got a couple or three million bitcoin holders globally right now, most with tiny amounts invested, and that has taken the price up to a high of over $16,000 already, starting from $0.02 7 years ago.
There are many other benefits as well, like being a part of a whole new economy, or ending the Fed and possibly even stopping nations from being able to finance wars. This is of course just as controversial and speculative as the price is, but you'll find no shortage of people that work tirelessly towards that end promoting bitcoin for those purposes.
Indeed, bitcoin has established its reputation to be the top cryptocurrency of this era and the generation to follow. By far in my opinion the greatest benefit of bitcoin is the finsncial dependency of low class people that they can have a chance to grow financialy even without the help of the government. Yet people can always take this opportunity to start their financial profitability in every way they can to earn.
