I don’t think fiat money can be replaced. It’s not that easy. And I also don’t think BTC can completely remove fake money. Because the cheaters always find a way and this is what they do.
As log as the currency is digital, technology will come and go frequently. Still there have been a rush by various companies to include a technology which IRL doesn't solve existing problems. Rather they do so to mark up their ICO sale and stuff.
Thanks for the great effort. You have figured out some really important points. I think we should keep these things in our mind before taking any decisions.
I think you should do proper research before investing. Otherwise those can scam you anytime. There are lots of scams out there and we should be careful.
