Secondly, the purpose of every investment is to give you relief when you are old. Bitcoin like any other investment is not exempted from this and will definitely liquidate it to cater for old age challenges and leave some as inheritance. It's irrational to burn asset even if you have no intention of using it. People out there need them.

And lastly, absolutely none. Looking back, we have seen how these tokens struggle up and down and believing something good will come out them in the next fifty years is just like a dream that one may prefer never to wake up.
