Can you show me your crystal ball?  It might we're the same.
But hey, just let you know the market movement is unpredictable same as Bitcoin price movement.

If you don't sure about the movement of the market price you can buy Bitcoin in a DCA way, this is a safe idea if you're afraid to be trapped in the bear market.  IMO, it seems there's no sign yet of the bull market and it could be next year still Bitcoin struggling to resist the price.
Speaking of the best time to buy Bitcoin, IMO, anytime you can buy as long as you never sell under the price where you purchase.
