I wished I learnt this earlier, but if you are trying to build a solid portfolio in the crypto data space, some major things you can do is:  

1) Build a sensible reporting dashboard on a fast rising protocol early  

2) Show that you can influence by using data in govy forums  

3) Make data tools. A little riskier because you need some good product sense but if done well its a good story to tell  

4) Whining about some obscure data quality issue because sometimes real recognize real (looking at you polymarket)  

5) Be super opinionated and robust in how you decide what metric you want to track and how its constructed. IMO this is your craft. Pay a painful attention to detail for this just like how a 3 star Michelin chef crafts whatever is on his plate. The end goal is to reflect reality so ensure that the metric captures reality.

6) Actually proposing next steps. Data is just an intermediary step in a process of decision making. Therefore it must always lead to somewhere and never really an end goal.

I think every week, one should review if you achieved any of these 6 points. I would definitely hold myself to this because I've not been aggressive enough in doing the above
