Maybe we should have the courage to make a decision even though it is risky, and for me it is more optimistic after Hard Fork then ethereum will be able to grow better, and because of that I am not thinking of selling right now.
Actually the OP has shown courage by saying that he/she won't hold and wouldn't take the risk, buying right now is the best option and then exit right after the fork because he/she believes the a big dump is coming. Not only courageous but has plans that might not be suitable for others like you, but for him/her it's a clear cut plan and I'm sure he/she is going to follow it to the tee. I guess that's the difference between noob and experience one. You need to have plan and execute it perfectly.
On a hindsight, I'm thinking that this Bitcoin bullish trend or at least this spike has something to do with Ethereum fork, somehow its really pulling up the price of Bitcoin as well, so let's see how it pans out specially after the fork is completed. Sketchy as this point because we are still in the bearish sentiments, but we will see.
