Altcoins to hold during a bitcoin rally?

[Red-Apple]

there are two types of altcoins,
1) those that are affected by bitcoin price, which means you should dump them, not hold during a rally.
2) those that are not affected by bitcoin price, which means they are pump and dump coins. and you can never tell when the pump is going to be with these type of coins. so again you can not tell whether you should hold it or not.
