Unpredicable job?
Yes of course.
But it is finaly easy...it goes up or down...just chose the right one...(lol)
Yes, it look easy but the opportunities won and lost is same. It takes a long to decide yes or no. 2 options but can make us rich or poor. If trading is easy, of course everyone wouldn't work and chooses trading, but it takes a good analysis.
Absolutely its very very unpredictable job for those who trade altcoins and same with stock market traders they don't find comfort of which is the certain decisions is the right decision they make when they trade because if you trade there were many considerations to take like fluctuation of the trend graph which you must have a brief analysis. In order to have firm decision you must read the current updates of your trading sites and be able to have inputs on the informations which is related to the graph trend you are monitoring so that no uncertain trades will happen and avoid lossing investments.
Even if you make decisions based on market analysis and calculations or experienced traders opinion.
There are many risks about trading that includes many factors that we cannot intervene with and it will be hard to say for sure whether the price will go down or up , but not for bitcoin because it is constantly rising.
