I'm sorry, but there is just no way bitcoin will be more valuable in 5 years.
That's like saying that the current iphone (iphone X) will be more valuable in 5 years than now.
Why on earth would anyone pay more for btc when there are so many better choices out there?
And you think in 5 years btc will still be the best blockchain out there?
No way.

But, in the short term, I still think btc has one or two more pumps in it.
It would be beneficial to still keep a btc based portfolio then sell it off when we see it hit 15k usd or more.
But after that, migrate your portfolio to something else.

you have to realize that all of these bitcoin hodlers are mostly basing their analysis off of their own experience, which actually isn't relevant anymore.
we are beyond the hodl era.
