You already said that fiat money can be printed out more.but bitcoin is only limited supply.in term of volume of fiat money compare to bitcoin it is better ofcourse because so much more money in all over the world but bitcoin  is limited only.but we know the value of one fiat compare to bitcoin.bitcoin is much more than to fiat.but in term of using bitcoin is much better to use bitcoin,easy to carry even a big amount you need it if you have bitcoin you can have it.bitcoin is better than to fiat in term of security.this is just for me.you have a safe place to put money in a digital wallet than fiat money that someone can steal.where ever you go you can cashout your bitcoin into a fiat money.easy to use wherever you are.
Thats my reason why bitcoin is better than fiat  or current money.
