I don't agree with this 100% because I think you can be successful in trading frequently but I think for newcomers it's very good advice. Instead of looking for a good trade to make each day do not restrict yourself to have to make trades. Look for the best opportunities and if there are not any on that day then do not make any trades.
What OP say is instead of consistent trading daily ,better snipe for single coin that you may bet with big chance of gaining.but lower portion of losing
And i agreed on that,because the more we trade is the more risk of losing,while if we limit into couple of times a week,then we might lose smaller possibilities
