When it come to making maximum profits, then low cap coins are the ones to go for, but like we all know already, investing in this type of coins also means taking a higher risk cus it is not guaranteed that the coin will succeed in the future, many or any thing can go wrong in the future and one will end up loosing he's or her money, but on the positive side, a 30 to 40 or 50 percent upward movement in this type of coins can turn one to an overnight millionaire which is not entirely possible with the high cap coins, so I guess it right when they say, the higher the risk, the higher the pay/money.
