Buying low and selling high is very difficult. In fact, no one is confident in saying that he can buy low and sell high in the cryptocurrency market. Sometimes I use trading support tools. But I have never been able to buy low and sell high
It is not difficult at all if you are a very patient and attentive person. In this case, you can invest in the cryptocurrencies when they are low, wait for some time, and sell your tokens when the bull run comes.
