I would say that blockchain data sites like Etherscan or Dune were great *initial* tools for my reporting. But I'm always skeptical of these tools, which can show more favorable or pessimistic outcomes depending on how the data is selected. That's why I spoke to experts at companies like Chainalysis and TRM Labs, but also direct sources in the market who were buying/selling.
I certainly learned that skepticism from the traditional art world. You can look at an auction and it says "$1 billion in sales, 97% of lots sold" but then you realize half the lots had guarantees and the low estimate was actually $1.3 billion. Suddenly you see a different story!
