This time I will be ready.

Hi, fortunately I was able to make 150% since the last BTC Bullrun, but that time I could not take advantage of altcoins, I bought projects without knowing much about their transcendence as Rose, but now I am different, I want to take advantage of ADA, XRP and XLM, among others not to be left behind.

What information media do you recommend me to make decisions as accurate as possible? They can be books, Youtube channels, websites among others. Any information will be helpful, thank you very much!
