No, it's always analysis. It helps to pick the right coin to buy. I always buy coins from polo and bittrex so the coins I'm trading aren't scamcoins and are not going to be delisted easily.
It is definitely true, it is about analysis, and it needed many skills for a successful trading, that is why it cannot be called guessing(not even educational). Skills for example will be research, focus, control, record keeping and most specially analytical skills. It is the ability of the trader to analyse information quickly and it involves many maths and calculations and technical skills. It is required to be able to understand the flow of the coins. First investment of time to read and learn informations about trading will be a great factor. Always stay ahead of the race and be ready to take on the market.
There are many things that people need to pay attention for trading is a very useful analysis for success when trading. Many people just follow another people to invest in the coin but do not know the detail what will happen to the coin later.
