The world is changing very rapidly, but rather it is changing technology. The appearance of our planet and people depends on technologies, even how we will think in the future and what decisions to make will depend on the level of our technologies. We are moving towards a completely digital era, and blockchain will probably play a significant role in this.
yes, I guess, there is no stopping technological progress and the crypto is the big part of it. The word is out - digital decentralized currency is possible, so no matter what happens with these coins here, but the crypto has the future in any shape.
