Your strategy is good, but a lot of traders don't have patience to wait they want to trade frequently. As they used to trading often, so if they don't trade for some time they feel unease. Anyway, you have to study the market and follow the chart regularly or you would miss the train of positive trend.
You dont have to trade everyday because you want to. Being a diligent trader is knowing when the buy and sell and what to buy and sell. I would stress on the "when" part of my statement more though. That means not everyday would be good for every trader. Thus missing out on a positive trend would mean you have lost that opportunity but you should not try to jump back into it. Let it go for now.
These things can happen and being not greedy about the lost opportunity makes a person wise. Rather keep track of that coin and enter when it comes back down.
This is true, many have the mistaken idea that a trader is always in the market and if you are not you are missing many opportunities but the truth is there are times in which the best thing you can do is to be out of the market, and if for some reason you miss a signal then there is no point in entering the market late, in a few days another signal will appear and you will make money in the market that way.
This indicates that one of the most important skills a trader must posses is the ability to wait and to not give up even if he suffers a number of consecutive losses because in this market is not rare at all to recover all the money you have lost with a single positive trade.
