I believe that this crypto is an option to get a quick profit. I personally have done that and happened in 2017 to the beginning of the year 2018. Maybe for many people, the gains I get are still very small, but I am fortunate to be growing with crypto.
It is possible to make money now very difficult because the crypto conditions are not the same anymore as the year 2017. What you say right we should use common sense. That we don't have to wait long enough to make a profit. However, daily trading can be a great option.
