I want to invest an altcoins but i dont konw how to predict if that altcoin will pump or dump. Can you give an advice on how to choose a best altcoin to invest.
You can invest some coin like : Ethereum, Dash, Litecoin, Ethereum Classic. You can see at coinmarketcap chart and make a prediction, then watch review at bitcointalk. Beware of Bitcoin Gold (because of scam). Oh if have no choice. Invest all your amount to Bitcoin xD.
