There is no need to force anyone to deal with crypto-currencies or use them in any way, the time will come and maybe in the future we will have to give up standard money and use digital currencies and technologies that are related to them.
Yeah, we are in a modern era now. Although there's no one forced anyone to deal with cryptocurrencies but time flies, and we don't know what will happen in the future. As you say, "time will come and maybe in the future we will have to give up standard money and use digital currencies and technologies that are related to them".
