Back then, I was frustrated with banks' hidden fees and the time it took to transfer money across borders. With Bitcoin, I no longer had that issue since I was able to send money at a cheaper cost within minutes (instead of days). Kudos to Satoshi for making sound money that enables people to be their own bank. Who knows if someday Bitcoin replaces Fiat in its entirety?
Could be mate, but as of now, bitcoin has a long way to go before we can even say that it's already close to replacing fiats, entirely! The good thing is that it's already in the process to be in that kind of state soon and bitcoin has already been with us for more than a decade now, so it's still quite early but let's be optimistic that sooner or later, bitcoin will be used more globally.
And as for the question of OP, bitcoin has been a big help not just for me but to my family as well in terms of finances, securing money to avoid inflation, and lastly, making my transactions faster, more secure, and much cheaper. I'm honored that I became aware of bitcoin's existence since it was introduced to me way back in the year 2016.
