No, it's always analysis. It helps to pick the right coin to buy. I always buy coins from polo and bittrex so the coins I'm trading aren't scamcoins and are not going to be delisted easily.
Analysis makes you know how does a particular coin will have a good future or not. So picking a coin that is not a scam coin can make you an income unlike the scamcoin that can make you lose or earn instant because its a hype coins only to scam and earn from traders.
