If Segwit2x fork was successful then yes, i think that even $10k is possible. Without it being 100% successful however this figure is very hard to achieve and unlikely to be hit for the next few years as a crypto winter may follow.

We're already pretty high up though and making another $1k on current prices is not difficult. All it takes is some whale to start buying and bag holding bitcoin to push that price upwards. If we can see any sort of major news from regulators that is pro-bitcoin then price could definitely be bumped right up there by the end of the year too.
