So even if they WOULD delist ERC -> WHO CARES? They would list it again when the market is demanding it.
Ummm...if a coin gets de-listed, that means there is no market (demand) for that coin. Where are you going to generate market demand if there are no exchanges that list ERC? The store? The store will no longer accept ERC because they have no way to exchange it for BTC (and then to USD or EU). So, if there are no exchanges that list ERC, its value is zero. I guess you can try selling your ERC person to person. See how much they're worth then.
First of all: There will be always one Exchange (I cant tell you which one for now) and because of that a real market grows by offering products and services.
Guesswhat: thats what money is invented for. Second i dont see ERC delisted on all exchanges
(Bittrex may be, but they do fast listing and delisting, policies are different and there are much more importent exchanges)
Exchanges are not unimportent, but they are the least natural market and the most unstable corevalue you can have.
People may believe me or not, but i know whats happening in the background of this Coin, and this one is a shure bet,
(no I am not one their team, if you doubt, maybe google helps about that)
if you hold the bags (should not be THAT difficult given this low exchange value ...or?)
anyway ... have fun!
