This won't have much of an impact when you are looking to trade a market that is subject to speculation, fear, greed, fud, insider trading, etc. In most cases altcoin trading is just guessing in what direction the market will go -- based on that people plan their moves. If people think they can read out a market that is subject to all afore mentioned aspects, they obviously overestimate themselves, unless they are a market mover, or closely connected to the people behind the coins and their pump groups. If that isn't the case, then 99% of the altcoins will be nothing more than a gamble.
