For me, bitcoin isn't just money, but a hobby. I read a lot of books about cryptocurrency, watch movies, communicate with new interesting people who, like me, are into crypto. That's the whole point. Someone sees in bitcoin only money and profit, but for someone, it's more than just a digital currency.
Not actually a hobby but rather an optional new way payment system that we can really be able to used conveniently aside from traditional money that we are depending
on since from the start.
It doesnt matter if you do take it as a hobby, main source of income or minding on fully supporting it when it comes to its true usage.
In the question on making persons life better? Depending on how you do deal with it.
Not all that do engage does make their lives better in terms of investment because we arent all winners on here.Some do earn and some do lost.
