As a long holder of silver, I was always hesitant of cryptos as I saw it as the 'One World Currency' and though I still see that true for Bitcoin, the blockchain technology is a good thing and here to stay.
Crypto is the currency for the Space Age, as paper or metals wont be efficent.
That doesn't imply silver will be worthless, infact - the amount of demand for silver will continue to increase until it becomes exstinct from use in all the computers using it for mining cryptos and providing P2P services.
This is the reason I cheering for crytpos. In essences it is cheering for silver, which is cheering for sound money.
Let's try not to loose sight of what we are here for!
