Cryptos are somewhat in a way very predictable, it is because that in the weekends they dip in many instances. So a trader will just look at this opportunity to buy the F-ing dip and then sell later. But of course it is not certain that the dip will go up again because of many factors such as news, rumors of upcoming crypto events, false rumors, etc.
But is is a fact that time and again it dips in the weekends because a lot of people just use the money perhaps to use also in the weekends, it is just my opinion but we just can observe that this thing happens very often in the crypto space.
Crypto trading is just easy to do but we have to be cautious about it and trade only if we are certain that we will going to gain in long term. Patience is one of the key in trading because if you lose patience you will make a mistake to buy high and sell low in the process and a loss is painful obviously.
But you are the captain of your ship so do not sell low when you buy high and then chase a pumping coin, it is not a good way to trade. Just consider your trade as an investment when your coin lose value and just wait for your position to get bought and in that way you will profit, you just have to look for the long term because cryptos are the future and most coins will succeed especially those that have a use like platform coins like steem.
