Silver is the second main investment tool after gold. Because silver broadly used in high tech industry, and worlds fossil resources cannot be increased, but only reduces, i think the price of silver in distant future will definitely grow.
Silver is the poor man's gold. If you look at how it has been performing in the last 5 years, then you really start to feel sorry for people that entered the market back then.
But if you look at how the price has been doing from the year 2000, then it has proven to be a more than solid investment, and at the same time a solid store of value.
Long term speaking, the price will surely grow, but if I look at the available options right now, and then namely Bitcoin itself, I will not waste any time on precious metals. It's a waste of time, period.
