Exactly, I ever thought about my trading is the best one for me, most suitable and perfect for me myself because it really gave me many profits continuously in several trading pairs. However one day, I lost much also because of that trading strategy. I thought about what was wrong with the strategy. And I realized that none is perfect. I should always do some more analysis every time when going to implement the trading strategy because sometimes, the market can change very easily. No matter how perfect we set the strategy, sometimes, it doesn't meet with reality. But at least, we know what's wrong with strategy and we can evaluate our strategy again.
We are also aware that successful trading doesn't only need a good strategy but also other factors that support it as you said. And of course, the management of risk and funds will also support the success of the strategy, including how we can manage our emotion very well.

IMO, this is good enough for implementation, moreover if we are going to do the holding, especially for Bitcoin. At least, it works fro me, but once more, not saying that this is also a perfect trading strategy
