Do you have your own spreadsheet to keep updated with the crypto world or do you use any interesting tool that already exist in the web? If so which one is that? Willing to share it? It seems that tools for managing crypto data/info is missing?
I assume that you actually mean all kinds of informations about bitcoin and altcoins or different news about whole cryptocurrency world.
I really enjoy in using Coindesk.com, it gives me signals to buy/sell sometimes, because they are pretty quick in giving informations.
You may also think about sorting all of your data about cryptos you have, and it is also a good question, because having everything well-organized is a really important thing.
I dont use any kind of tool, but Im using folders at my PC for saving the most important informations and news. I call them with different names, and i make up the setups that are comfortable with me.
