Luck is actually a particularly interesting topic. The wave in 20-21, entering in September 2020, will be exactly 100 times stronger by November 2021. What is earned on the chain cannot be considered luck, it is deserved for strong gambling, but ETH revolving loans are indeed luck. When cake mining could mine 40000 units in a day, I was thinking, if I lose money, can I still get back up? My own answer at the time was: not necessarily. After 4 years, the coin circle has gone from defi to inscriptions and then to sol meme, which is a victory of methodology. Although there are many pains and ups and downs in the middle, and even almost poverty, my answer now is that as long as there are new trends/new gameplay in the cryptocurrency circle, no matter how many times I lose, I can still rise again. This is not a matter of luck, it is progress over the past four years. In addition, the biggest component of luck is ETH revolving loan leveraged betting on the market. In the middle, I have suffered heavy losses on many contracts. For myself, as long as I don't touch leverage and contracts, I won't encounter major problems. So, I will constantly emphasize that contracts and leverage require professional traders to have very strong risk control and strict position management in order to play. Of course, there are many professional traders on the platform whose path is to stabilize profits. I also respect this and often read their content to provide reference for the overall market trend. So not touching the contract leverage is just my personal principle, which also applies to most novice traders.
