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.
It's more or less over now. BTC gas managed to get up to $6.8k now, do you think BCH is capable enough of making BTC fall again, No. At best people can expect BCH to keep above $1000.
