Yes, while many people assume their assets are protected, there have been historical instances where governments have seized citizen property stored in banks.
I agree. Gold and silver are still better than banks because it rise constantly, unlike in the banks that it differs on what plan, on which bank, and other factors. Still it is best to invest in cryptocurrency because of the potential of growing and also this is the future of all of us, the digital currency.
In my own opinion, gold and silver will be only better than banks if the scale of increase in price is much better rather than bank's time deposit feature if you place money on them.
