Bitcointalk, the perfect website for learning about trading as well as the source of gaining knowledge about crypto currency. There are many thread already created on this trading discussion sector. You can check those for know about trading and ask about trade related question here if need. You can a google search if you need other website to know more
I think it is better to learn here in the forum than doing some google searches.
I guess you could learn the basics in trading when you do google searches but in the long run, I think it is better for you to follow a thread here in the forum especially if it is about cryptocurrencies since most of the people here are experienced to the movements of the price. But the best of them is the knowledge you get while you get through.
I just take good moment when trading by checking and keep going on with twitter and telegram good or bad news when entry on future trading, always have an update when some coin have good news like burning supply coin, have new partner and in twitter you will get always bad news when some coin got hack. Just check your twitter and always get notification on some coin you think become worth for holding or investing, I check twitter each hour and looking which one coin have new or good news for buying and will make short position on future after bad news on some coin project, until so far always worth with get profit.
