This is a very bad technique that might cost you a lot of money in the future. Instead you should always have a trading method (whether it's fundamental, technical analysis, or whatnot) and keep an eye on the trend. If you're trading based on your feelings you'll lose anyway at some point. I don't even agree with saying that you don't lose (or win) as long as you don't sell: if you don't have a clear trading method you can just consider any investment made a loss, from the moment you click to change your base currency or token into something else that you don't know how to trade, and then observe how it goes, which means that you're losing anyway, until you're (maybe) winning.
