That depends on the tokens you have. If you have, for example, worthless tokens that seem to have no future development or progression, then just convert them to ETH and hold it for the long term. However, if the coins you have have the potential to grow or increase in value, let's say if they have active developers on their team and a well-written project roadmap, then do not convert it and likewise, just hold it until its price rises.
Lets just say that 1M token is worth $100K and every time the price rise a cent you get to earn $10K, would you be picking up ETH to be on the safer side or chose to keep your 1M token worth $100K?
Its a situation where having ETH is something to brag about while having the 1M token is something that will make you unimportant.
