n00b here, been looking at coinmarketcap and worldcoinindex highest daily gains but don't understand how to jump on something that is going up 100% at the 20% pump stage?

PLEASE can you tell me how this is done? do you set alerts on tradingview or something similar?

I can only currently buy coins listed on cryptopia, bitstamp, gdax or binance.

how do these tiny coins gain 200% in a few hours 'randomly'?

logic would dictate that looking at a list of coins and some have gone up 10, 20 or 30% that there would be movement either way but they just seem to sit there inert?

how do you jump on the rocket ship??
