Is it time to sell BTC for some BCH ? Maybe sell 25% holdings of BTC to buy BCH ?
I don't know what to do as I don't have any BCH... what are others doing
No no no, bad idea. What would you do if you have BCH anyway? You shouldn't buying because the price is rising. You're panic buying and it won't gain you any profit. You shouldn't react that late to market action. What others doing? Well people who panic buy are buying at a high price and left bagholding BCH.

If I send 0.2 BTC to an exchange will the BTC transaction get confirmed ? Because there is a big backlog in transactions ??
With sufficient fee, yes. It's just that the fee will be higher than normal day.
