Time travel hasn't been invented yet, but in 40 years it will be. Bitcoin will be massively illegal and mining will be impossible due to sophisticated tracking. The mob sends ASICS back in time to guys like me, called dumpers. We mine on our ASICS from the future and dump for cash now. When everyone gets their ASICS and dumps we buy back up like crazy and send the coins to a BTC address in the future.
This is called "Closing the Dump"
But then when everyone is rich in the future and the bitcoiners have bought out the government, they will never send the ASICs back in time because they wouldn't need to because they're rich already, but then no one would mine with ASICs now and no one will be rich in the future, so they will send ASICs back in time, but then they would be rich and wouldn't need to send ASICs back in tiime but then no one would be rich, so they will send ASICs back in time, but then they would be rich and wouldn't need to send ASICs back in time but then no one would be rich, so they will send ASICs back in
