Do you need articles on technical aspects (wallets, exchanges, etc.?) or trading ones?
From your question, it seems you need trading tips.
I would suggest you to learn some technical analysis, first. On the internet you could find several resources, books, etc.
Personally, I like Elliott waves and sentiment analysis (basically, buy when everyone is depressed, sell when there is euphoria).
Youtube is full of people who analyze the most promising coins of the year. I would suggest you to, ok, view the videos, but think with your head. Has the project behind a coin some future or not?
Bear in mind that it is complicated to follow more than 5 coins, as you should monitor them. My suggestion is to start focusing on the top 5, make some paper trading and, when you will have the skills to distinguish if a project is good or not, invest in other altcoins.
Finally, I frequently hear that a newbie should lose at least 50% of his/her funds, at the beginning. I can confirm that it is true. Volatility in crypto is extremely high, and, if you don't have the right mindset, you will risk to sell at loss, just before the market recovers. Hence, before investing, think how you could react in case of huge loss. Would you sell or hold?
These are my 2 cents, but I think the others could have other suggestions for you!
When I was a newbie Youtube was one of the favorite site I go to. There are a lot of people who gives tips and tutorial on how to trade. Since cryptocurrency trading and Forex trading are similar in concept you may watch forex tutorial as well.
Also my personal advise is do not be eager to trade make sure that you actually are equip with knowledge on trading because this is a dangerous game. If you do not know what you are doing you can be wipeout in an instant. Try a demo account first to feel how it is like to trade. There are many platforms that let you create a demo account.
Once you are confident with your skill then create a real account. Just a warning trading in a demo account and a real account is very different STRESS wise.
