I guess the fact remains that if the devs don't come back and put some work into the coin then nobody is going to buy it anyway, no matter how many exchanges it was on.
There are lots of almost dead coins , with no updates from the dev for months that are still traded.
It's pure greed that drives alt coins , and that needs no development.
True I suppose. But most of those at least had some kind of unique feature that created some initial hype thus giving the coin an inherent value (even if only small). This coin really has nothing unfortunately.
Check the bottom of coinmarketcap.
Coins are different from any other investment. Unlike the shares of a company that doesn't produce anything or perishable goods that rot in a few days or months you can hold the coin all your life.
And if nobody with huge stash is selling , there is no huge drop in the price.
That's why some coins "survive" and they will do for a long time.
