The lesson that can be learned in previous years is to be patient. The word is very simple but as long as you are patient with cryptocurensy, many are less grateful and greedy. A trader and an investor are not the same but have the same mentality to earn, both have different points of view, an investor may wait until the market is good while a trader must quickly do something to avoid further losses and lose a lot of assets.
What happened in 2018 is indeed something that will not be forgotten, where the market was completely destroyed, many investors panicked and sold
all their crypto at a loss. But if we can be patient, it will generate a large profit if we can hold coins until this year. I agree that the most important
lesson we can take from the events of 2018 is to always be patient, because patience when investing in crypto always brings good things.
The most important thing is that we choose coins that are potential for investment, So if the price falls, it won't take long for the price to rise again.
What we need to know is that making a profit from crypto cannot be instant, it is a sometimes lengthy process, so patience is the key to success
when investing in crypto.
