For me. I think a lot of Cryptocurrencies is already invading or conquering our whole world. I do research everyday about news in Bitcoin and i was totally shocked when i see theres a lot of incoming coins or new altcoins like Bitcoin Cash(BCH) and later another new altcoins will be coming the Bitcoin Gold(BTG) in short and i think this will continue and a lot more new coins will coming before this year end.
I do not know much about how the market runs or how biggest people behind of it work hard for it. But i think a lot of people will go crazy and more people will to their best to get those coins. Thats why i think cryptocurrencies gain more a lot of popularity and reputation to many peoples worldwide
What is your Opinion about this?
Cryptocurrencies will definitely shape the world for years to come. Apart from a few exceptions I doubt that alts will fare all that well however. There's simply too little use for most of them.
All fiat is going to be replaced by cryptos. This is not a secret, but rather an obvious fact. Because cryptos can be easily tracked unlike fiat.
While opaque for the general populace, fiat bank transfers can also be easily tracked, assuming there is no conflict of interest. Any obfuscation method that gets applied to fiat bank transfers can be applied to cryptocurrencies as well, but is only necessary when transitioning into the traditional banking system ie. when exchanging cryptos for fiat. Apart from that there are alts that explicitely aim to subvert trackability.
Regarding cash it seems like governments are mostly trying to nudge people towards using bank transfers instead, achieving the same goal without replacing the current system with crypto.
