Unlike last time there was a dip, there is no real reason for this one, other than a random snowball effect it seems. I would keep holding, though if it drops below $9,000 it may drop even further. Or, if you're worried. Just convert to USDT now, then buy back in when the price is clearly recovering.
Hope BTC will keep the price over $9500 and even $10000 next weeks!
I don't see any particular negative factors that can force another market fall.
