I agree with the opinion that the future is cryptocurrency and blockchain. As more and more people and companies are convinced that this technology is convenient and safe and see its obvious advantages.
Yes, I also believe in the great future of the cryptoindustry, every day more and more countries and people are starting to come to crypto. Blockchain technology - will change the world, it is happening right now. I think that in the near future, crypto will be everywhere.
Unless there is better, it looks like a good choice. But in the future it is possible to have better systems. Also, if you do research, you can see better systems than the blockchain.
