Dear p4ekin,
I think you are not fully aware of the potential blockchain tech usage and how it can disrupt every industry by removing centralisation. And this Blockchain tech came from Bitcoin only.
And Bitcoin has the capability to replace Gold reserves and fiat reserves.
I think he's aware,he's already a senior member and he's not aware? It's questionable. Maybe he/she means investing his/her money literally. But Foolish is not a suitable term. If you will invest be sure that you are an intelligent investor, timing, trading and everything. Just like me, I don't invest any fiat to covert to bitcoin but I invested my time and knowledge to join campaigns that are actually have highest potentiality of success. I will always support technology.
