Up up up! At least for the main ones!
There are prognosis for BTC value at $50,000 within couple of years.
Would be nice to have some BTC at that time :)
As the total amount of BTC mined will be less than 21,000,000 and there are like 8,000,000,000 people
when you would own 1 BTC it will be probably more than 99% of the population
