both are heavily manipulated, and gold does not rise in the manner you have described, does it? it has been at $12-1300 a zip for like ten years now, right.
Maybe not in that way, but long term yes it does, in 2012 it got close to $1900, I think both the USD and AUD were around the same amount at that time 2012, not that has anything to do with it though, but yet again it kinda does, because it's not far down from where it was for Australians at that time, we were in a mining boom, when the rest of the world was crashing as well, early 2016 it struck a low of $1100 USD, it's now $1266 USD, which would be $1653 in Aussie dollars, looking at a 15 year time frame though, gold is up heaps compared to $319 USD in 2003, it is 4 times the amount that, now if it rises another 4 times in the next 15 years, it's a wonderful investment, and it's a safe one, because it's "precious metal." So in the past year bitcoin has been slaughtering gold, but it's at $16000 at the moment, it has high jumps and the big falls all in one day, yesterday it was at $21000 at a certain point.
But the difference between Bitcoin and gold, is bitcoin is a digital internet currency, it's not a rarity in anyway, gold is a precious metal, and can be hard to find, unless if you have a mining operation of course with all the heavy machinery and stuff, but still the amount of gold you find to a tonne of rock and dirt, it's rare stuff, so in that way gold is a safer investment. Gold panning can even teach you a thing or 2, about how hard it is to find gold in the creek bed, even if you are experienced or lucky enough to get any gold in your pan the amount of grains of black sand and other minerals is far greater than the amount of small fine gold, and you would need quite a few successful pans to even amount to a gram or 2 of gold. You only need to go on the internet to find a bitcoin.
However mining shares though can be even better, if you get with the right mining company at the right time, at a cheap price, you can 10x to 30x your money over from anywhere in 2 - 10 years, but if you go looking for mining shares, don't go to the big guys, their shares cost more and they are less rewarding by far, have a look around at some of the smaller mining companies on the share market, and you will find some of their shares are pretty cheap at the moment, they can be like 500 times cheaper than the big miners or more, and much bigger gains can be made.
