It is possible, but not now. You know the price is going down again, BCH may have a rally soon, but 0.18 btc is undervalued, I think the reasonable value is 0.25-0.3 btc.
It's now or never. If BCash doesn't manage to take over anytime soon they will run out of coins to manipulate the market with. Hopefully it'll just disappear, BCash is a scam.
