Futures contract close and settlement timing

[CryptoXL]

It seems to me that any regular traders want to watch the timing of the close cycle of the futures contracts. Because there will be likely a dump following the pump. BTC has pumped $3k since open of futures and I see it pumping another $2k within a week. It looks like we will see BTC at $20k.

When is the close date of most recent upcoming futures contract. That is the date I want to be watching.

Anyone got it calculated when the close is expected?

Based on what I read at CBOE the close is the Wednesday of the third week of the month?

But I really don't understand how it works.
