Dollar valuations are useless. Some coins are valued at a really high price, but that's because their supply is really low. The overall marketcap is low compared to the ratio of supply:demand.
You should be looking at the fundamentals, available supply, final supply, inflation rate... and then decide if the coin is underrated or is just another shitcoin about to stagnate forever.
You seems like an expert in trading, with alot of experience in this crypto currency. I am just trying to acquire the knowledge which can enhance my small investment. If more ideas can be delivered by you then it can be helpful for many of us.
Cheers
