In the world of cryptocurrency, everyone wants to make more than 100% in one transaction, but this is not possible over the course of a long trade. You can never sell coin at the very top and buy it at the very bottom, and then greed will kill you on a certain day.
We should not really consider it luck, we have option to choose which coins and were the one to decide where and when to put it so better try until you make it work and profitable.
Feeling the need to have a good luck in other words depicts the absence of strategic decisions and the consideration of different situations you might face in crypto business. I believe that one should not wait for luck and should rather make use of the available opportunities in the current market.
