I spent some significant time last year researching Bitcoin and ETH, and tried to learn what is the concept behind it and how it runs and why value going up etc etc, now i do research on altcoin, and trying to find some good coin to invest.
Learning about new altcoins, ICOs, crypto related projects is a never-ending story. If you don't want to be out of the loop you will need to monitor the market every day.
I remember that coins which were on top of the coin market cap chart at some point are now barely staying alive - with proper research you can mitigate your loses here.
Recently I am focusing more on learning about potential legal regulations of crypto more than learning about new coins though.
There is no point in earning money via crypto when you won't be able to use/withdraw it in the future due to problematic regulation.
