You will never understand the real taste of anything until you do it personally. I won't suggest YouTube to anyone. Trading process we can learn from demo trading account as Instaforex offers 5K USD. Buying and selling this isn't such complicated work, but Coin selection is complicated. I would suggest this person stay focused on good projects.
OP is looking for Daytrading and not for Holding or other related strategy in crypto so looking or Good project wont let him trade in day basis,though YouTube is not that best way to learn yet for Beginners and noob that is a good help to learn.
and also those free Demo can also help them experience trades and how this works.
sooner they will learn little by little ,there is no need to rush because this is all about our money to keep safe.
Why don't you try to search in google about how to learn trading cryptos, there were many sources like the articles, forums, videos like in the youtube. If you start to trading just try with a little amount of money just to train.
basically trading is only buying at low prices and selling at high prices. Well, that is the basic theory. however, to see how people trade, there are many examples on YouTube. if you want to learn price analysis, I suggest trading directly. then you will get an idea for that.
In general, you need to spend time research and watch some video tutorials on Youtube because this is the number one media for you to study. Also, you can search on google to listen but share from the previous ones because surely they will have much good advice for you. I have stayed in this market for a very long time, and I am constantly adding new knowledge to become better and better.
Time and effort will always the good way to make a money in trading,this is the problem of those who fails in trading,because all they want is to make easy money things that is not applicable in this market.
we need more time to learn and more time to earn.
