I'd like just to add some few stuff, for the previous answers where fabulous.
First of all, I consider the Bitcoinwiki to be a really nice and complex place to seek for information:
https://en.bitcoin.it/wiki/Main_PageThere you will be able to understand many complex concepts related to blockchain, which I find to be essential to achieve a full panorama related to how the crypto world works. Why it matters? Well, if you are going to use something, why not understand fully how it works? Maybe you can get some nice ideas from it.
Secondly, in my experience, day-trading can be something exhausting. So, to me, there are several points to follow:
1.- Never invest non-expendable money. If you are investing the money you need to eat, then you won't be able to have a cold-mind.
2.- Choose well and learn as much as you can about the coins you are interested in, but never fall in love with one. Investing is not about being "loyal" to any project, but to try to get the best profit. So you don't need to love any coin, you don't need to have any kind of feelings towards a coin.
3.- Make some proofs even before putting in there your very first dollar. Why? Because you can be wrong, as everybody in a training process. So just play for a few, enjoy yourself, watch the market...
4.- Distribute your time. You don't need to be all day thinking about trading, this is insane, and you can be obsessed and, with that, unable to maintain a cold-mind. If you decide to invest, then maybe it is better to stay away from your investments (mentally) few hours per day, so you can go back to them with the clearest view. To me, it was one of the most difficult lessons I have ever learn, 'cause I'm a really obsessive person. But when I understood it, my investments were much better.
All the things that have being said to you are really good points,
I hope you have the best of the lucks. Trading, somehow, can be little like gambling, so consider you can fail sometimes, but, with time, surely you will succeed.
Best of lucks, man!
