China is already launching their first "crypto", Facebook is doing the same, Microsoft, Amazon, Apple and Samsung are actively investing into blockchain technology and will maybe launch their own crypto. Blockchain is here to stay, crypto must fight for survival.
China has not launched its tokenized currency yet, they do not share when will it happens too. It is too early to talk about them since the process might take a year or years to finish their regulation and product.
Blockchain technology is the future, it will help to digitize our lives and this will facilitate access to any data and it's important, it will help in the fight against corruption. Over time, cryptocurrency, as a form of digital currency, will also be accepted by the world community. It takes time.
Blockchain is the future but I do not think blockchain can help us fight against corruption because the corruption itself has nothing to do with blockchain.
and I doubt cryptocurrency will be used as a method of payment in the world. Personally I think it is just going to be another asset.
