Don't post on a forum asking for financial advice. You're literally asking shitposters to decide your financial future.
When it comes to investments, you should be moving slowly. You shouldn't be chasing price. Selling all of your bitcoins for a shitcoins? You better slow down and think this through. Why would you invest in BCH? Why is it a superior investment to BTC? Temporarily cheaper fees, that it? Bitcoin is the most utilized network in the world and offchain mechanisms with lower fees are coming.
Some people see Bitcoin Cash as an attack on Bitcoin, to the point where they won't trade it. Personally, I don't mind. But for me, it's just a trade, not an investment. Seeing the price of BCH double in a day can be an emotional experience, but remember what happened the last time around. It brutally dumped afterwards, and Bitcoin went to new highs. Be prepared for that to happen again.
