Yes, I dumped all my Bcash spread over the first three pumps and I am happy I don't own anything anymore. Actually I hope some more attacks will take place and exchanges will delist these coins and they will die out. This is bad for crypto overall, newspapers will write that bitcoin is hacked or something misleading like that. Beside that just one PoW chain is way more efficient and secure. Now miners could destroy one coin with the intention to mine another coin after, while when there is just one PoW coin the hardware will become obsolete after they destroy the coin, so they won't.
