In my opinion, cryptocurrency is future of currency. Advantage of cryptocurrency is no inflation and limited, no one can create more.Fiat money was control by government and which government is weak on control currency, fiat money lost price and inflation.But cryptocurrency still new, cryptocurrency need time to develop.I think you can invest on BTC.

It is useful in a sense that it creates a community or makes people interact with each other and evaluate something. It could be a way to make money without risking any money at all, or it could be a way to learn more things, how things work, or even communicate with people.

Are Airdrops and Bounties really leading to a successful coin? There are so many out there this time.
Or are they mostly shitcoins, disappear or using your emails for phishing?
Have you ever participate to one with high profit? How long was wait for that?
I think most of them are just bullshit and time wasting and not worth putting some effort in.

Investing in cryptocurrency is a really great decision. It has helped many people make a good amount of bucks. And this is even one of the best times to buy. Simply because the prices have fallen relatively low. But you must get to know what you're getting into. Calculate the risk and decide for yourself if it's worth it. Don't base your choices off non-substantial variables. Don't invest because it is the thing in vogue now. You might end up losing a lot of money. Get proper information, watch videos, read books and articles before you put in your money. It's valuable afterall.

Firstly you need to understand what exactly you want. To save money or multiply them.
If the goal is to save money, then it's better to invest in fiat. If the second one, you can try to invest in crypto.
The first option is good because you're practically 100% secure your fund, it will bring you no surprises.

Investing in FIAT currency you mean forex trade? Forex is manipulated more, bitcoin is global, harder to manipulate.
You shouldn't listen to advices like that, you should research it yourself if its worth to invest and WHY. Why is the question most people that invest dont ask themselfs, they hear about cryptos much and then invest, without researching why, then they are vulnerable to sell instead of HODL.

Pretty much what HeRetiK said. If you're asking us what the advantages are of investing in cryptocurrencies, then you shouldn't invest because you don't know much or anything about cryptocurrencies at all. If you did, then you should be able to answer your questions yourself.

What I always suggest to people new to this space: study. If you're not willing to, then forget it. Invest in something else you understand instead.

Fiat has nothing of value behind it. It has value because people use it and trust it to conduct transactions. Once it was moved off the gold/silver standard it lost all value.

Cryptocurrency is backed by something tangible, (Blockchain Technology).

Huge difference between something that has no inherent value and something that does.
