Never give in to the temptation of selling since the present value is just actually the tip of the iceberg.
Thanks for this article, it is somewhat soothing for my nerves that professional economists believe that bitcoin will rise as high so fast.
But I am still afraid that Bitcoin value gain is not simply matter of following Moore's law but basic laws of the economy as well.
It is not like Bitcoin is only viewed as technological game changer, whole economic system is linked to it, any drastic changes (e.g. price spikes, rapid growth)
might cause whole system to collapse or reverse.
