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.

I'm with you on "portfolio". Although BTC forms the main holding, it's prudent to spread out the risk by having other coins and token too. And bought only with money that we can afford to lose without getting into financial hardship.
Mine is the same, big chunk of BTC and smaller chunk of ETH, then another 20 or so cryptos... best of luck with your investment!
