Anyways for making decision you not only need all the current data but historical data too. By checking what event caused what prive movement in history will give you some idea, how the market can behave in future if same events happens again.
In my opinion, you can not rely on historical data for cryptocurrencies. The market is strongly news-driven, positive news can cause massive leaps in the chart. The historical data can only be interpreted if one also takes into account the news situation in relation to the respective price fluctuations. This fits OPs "do your own research"
