Like you I am not worried that crypto coins will be the future. You mention China and India taking steps to make them illegal. I think that might help these countries in the short term but will backfire in the long run.
Also here in Switzerland the government wants to support further research and development of blockchaintechnology and crypocurrencies. They want us to become the crypto country (we already have the „crypto valley“ in Zug). So no. I am not worried of my personal investments.
