From an investment or technical perspective? I'll assume investment.

I do it the hard way as the summaries often leave out a lot or bias facts. Especially mass media.

Start with the coin official site. If you like the pitch, skim the white paper. Abstract and conclusion tells you a lot.

You can learn a surprising amount from just the tone of the founders.

Next, check out the community. Usually Reddit or Slack. Read both sides, e.g. for ETH and ETC. As a general rule, don't invest in something until you know its downsides. If there are no downsides, then you don't understand enough about it.
