The Blockchain is a great technology and for the time being we can expect that emergent nature of the community will overcome all the bans, governments and restrictions and to continuously change technology on its way.

Having said this it's very difficult to bet on the right crypto, which one will be the one that will solve the specific issue of the moment?

My suggestion would be to:

• yes spend time to select cryptos and tokens, look at graphs and read about teams and regulation
• but always maintain a portfolio of cryptos so that you are not too exposed to idiosyncratic risk

For those interested I wrote a post on the gains from diversification.
