Gold and high precious diamonds would be a great alternative if you want to. Its worth wont go down but up in such collapse simultaneously in the bank and cryptocurrency. But to hide it on the safe is a different story, it needs more than security but also luck. So before doing so, make any plans in advance about those area of putting those or you might be on hide and seek with criminal elements around.
I agree with Gold, as in gold jewelries. I remember I have like 50 grams of gold before and its like x5 by today's price. So I think gold and other precious jewels such as diamond is a good investment besides crypto's because the price could multiple many times and can grow exponentially overcome. But just remember to keep them as well in a safe place just like your bitcoin private keys. So that it will not be stolen by someone. And the good thing about gold jewelries is that its easy to pawn, so if you need an immediate cash, you can just go to a pawnshop and immediately exchange it for cash if you need money in an emergency or something.
Diamonds are a key, you can hide a baggy up your ass, and it sets off no dectors, the new body-scanners may mean you need to tape them here&there, but still the idea is the same,
CIA has been moving its loot for years with diamonds, its the only way to move large amounts of cash without setting off metal detectors. Modern back-scatter tech probably catches diamonds, but you could always keep them on your glasses or watch, or a ring, or any fake costume jewelery that dumb TSA people would not want, These days with the way body scanners are working, I think hiding a bag of diamonds in your ass would no long work, hell I tried to keep a wad of 100 dollars bills rolled up like a joint on my ear, and they caught it!, they're good!
Obviously CIA is not really used for a the betterment of one countrys security but to do this illegal things for many years now. But we cant do anything about it but to ignore them or not to talk about theyre illegal doings for our safety. This controversy been in circulation more than a lifetime but they dont care anyway to even talked about this.
Really funny, baggy up your ass. It sounds painful, then if it is diamond how can I resist or refuse to sacrifice that crown jewel and pain.
