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.
