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.
I think if pumped and dumped, no one actually know when it will be. But if you see some project do their updates, like big news, good news it will be pumped. I think new tokens easier to predict than old coins in market.
