Lol, although we can't make prediction for BTC price, but wait until BTC price going back to $200 and hope it again to going up to $400 is nearly unrealistic (in my opinion).
The lowest price/bottom is around $300 or more.
Yes. I can't see any factor that the price will touch again at $200 mark with the current support its getting now with the current price and even back when it stays at $260-$280 last month. Plus the upcoming halving. No reason at all to wait for $200 just to buy.
