Here is a simple test to see if your altcoin has real value...

What would happen to the value of your altcoin if Poloniex delisted it?

Or Bittrex for that matter.

Both of them have too much control over which coins live (in case of a random listing) or dies.

They should at the very least just have a warning that they want more volume from the coin so their communities could chip in.

Optimally, they should have clear rules and conditions to keep coins listed (average volume, wallet stability, node count, etc.) so there would be no surprises.

i agree exchange are way too powerful today, they can control almost all the alt, and they also create and pump their own alt, and also manipulate all the other without you even knowing, i'm all for decentralized altcoin exchange, should be integrated directly in the client, and this would also encourage people to run a node and support the network

Embrace reality, dude. Learn to trade worthless speculative bubbles

this is the reason why Blocknet will be a top 10 coin. Once they deliver on their true decentralised exchange everyone will use it as it also will be free to trade and transfer!

they do have a warning and a system for delisting coins.
on bittrex that i trade, there is a weekly average volume. i think it is something around 0.01BTC but i may be wrong. and they do give a warning for it. there is a clear text on top of the market that is in danger of being delisted. sometimes they come back with volume and sometimes they don't and are removed.

i have seen far too many empty promises like this and each time i am disappointed like the last.
