you need 5MIO votes to get on the exchange right...
so DOT is listed like vote ? couse that cost 0.7BTC ? am i right?
for 0.7BTC we get new exchange

for DEM
yes, for immediate addition to Cryptopia's exchange
But it may cost much less, it may be 500k or 1M DOT, depends how much the other listed coins get within a week
But efforts need to be synced in order to avoid them to be wasted (due to votes reset each end of week)
