Yes, depending on what happens with silver and gold, small coinage can be very valuable, we just don't know just whats going to happen with the metals vs crypto, I cannot recommend any market but yes I do put into stocks also, but with that said, you just have to put a little in everything to be able to try to survive. a crash is imminent and being prepared is key.
I have heard of people saving other country currency i just don't believe in anything but either survival techniques such as what to prepare for in case of a hurricane, that would be food and supplies to survive like a generator, the same goes for silver and gold in the case of an economy crash.
With crypto its very volatile, but you can become very wealthy IF you play your cards right, but it does carry very well value!
I also like that you buy on what you like, i do the same, there are certain coins that are rare, low mintage or just something you like, great video!
diversify is the right state of mind.
