Bitcoin is the best alternative way to save money, with Bitcoin you have control over your savings because it's your wallet and your key and you are your banks!
Bitcoin is digital currency which in other words can be called electronic money and mostly treated as an asset rather than an alternative to Fiat.
No matter how much Bitcoin you have, I'm very certain that you can't spend it(Bitcoin) without having to convert it to the regular Fiat accepted in your country except in few countries where it is accepted as a legal tender.
My country is going through a very huge financial crisis and I have Bitcoin, but yet it doesn't make any difference as both those that have Bitcoin and those that don't have are all going through same Fiat scarcity because I still have to convert my Bitcoin to Fiat before having to spend it.
I just want to express that Bitcoin isn't an alternative to Fiat in my local community.
