You have to spend more times for analysis price action and fundamental of each crypto, currently there are some altcoin was going up to 100% just in 1 or 2 days, and this good situation to make good profit. To earn maximum profit we should more focus, keep patient and set target profit monthly and avoid greedy.
You know when people say they do not have luck when it comes to trading; I tend to realize how they have actually ended up getting it all wrong right from the start. Trading is a profession and every profession requires learning and because a lot of people take that with levity, they tend to get burned at the end of the day.
Gambling and trading actually work together in some ways. if you are trading without a strategy, you are gambling, and that will always give you the worst experience you can ever imagine which is what makes people like the OP depend on luck, but on the other hand, if you trade with knowledge and great experience, then that makes you a professional and in this way you are not trading based on what you expect luck to give you but based on what you know.
