what would you recommend will be my first stages ?
Purchasing ETH or anything else? start checking ICO's or try to trade a bit ?
What is your intention in investing in crypto? Do you want to trade actively or decide to hold it for the long term? If you want to trade then you should start with the basics first like learning the concepts. This is the best site for me to learn trading
https://www.babypips.com/learn. I can see so many people jumping into trading and deposit in exchanges immediately without even knowing what is bid and ask so it should be step by step process.
If your intention is to participate in ICOs then you should make sure that the ICO has a potential. I see some threads in here about ICOs.
