IMO price is going to be pretty high and definitely should be a few all time highs broken by the time 5 years goes past.

I would say with confidence, at least $15,000 per coin by 2021-2022. However just don't expect bitcoin to get all of its gains from 2018-2020. Most of the gains are going to come from the halving year and the year after.

If major institutional investors come in then $20k+ per coin could be possible as well.
