I believe it could be more. If the steady stream and trickle of upward price movement is any indication, we could be potentially facing EXPONENTIAL growth once this goes mainstream. If this year bitcoin grew by 1800% imagine how much more it could grow in 2-3 years time. Only very few people know about crypto if you look at the potential population and soon people complaining about high prices now will soon be left behind regretting they didn't buy cheap while they could.
