I see Gainer & Looser every day in Coinmarketcap. I always try to know, which coin will Suddenly pump? I've read a few article, But I can not understand it easily. Many people say learn Fundamental analysis. If you have knowledge about this topic. Feel free, You can share your skills & knowledge with everyone.
It is impossible to know such a thing, every day there are coins that go up in value despite the bear market in which we find ourselves to be in and many people like you think about all the money that they could make if they could predict when that is going to happen, but those movements are unpredictable because in many cases those coins are being manipulated by pump and dump groups and if you invest in that coin when it has gone up already you're going to lose your money when the price of that coin crashes.
It is way better to concentrate on trying to obtain consistent profits over the long term instead of a few lucky winners, this may seem a very slow and boring process but that is the way most successful traders make money in any market.
