Since, you bought at pumped price, go long on your holdings. Forget your bitcoin at least till Q4 of 2018. Price will go uptrend by the end of this year easily. If you are interested in trading or investing more, get in the coins after G20 summit and forget your older investment as for now. Right now buy more to average out your $19k buy range.
Many of those that bought at the very top of the market did it for the fear of missing out so it is very unlikely they are going to have the patience to hold for that long which is a shame because I'm pretty sure that in a decade people will lament not buying bitcoin for 20000, can you imagine that? Buying at 20000 would seem cheap.
Waiting from this time to when the price will be $20000 again is quite uncertain and nobody scan truly say for sure if this would happen this year or next. But one thing for sure is bound to happen - BTC will survive.
