I am by no means an expert so I cannot tell you exactly what is the best course of action. Even if I was an expert, there is no advice guaranteed to work in all circumstances. You should do your own research on this topic and seek out the opinion and advice of people you trust and have knowledge in this area.
Having said the above, it does not take an expert to know that if the government keeps printing lots of cash and that cash is backed by nothing, it will depreciate at some point. This happened in the inter-war German state and Venezuela more recently.
Whether an investment account will be safe depends on a few factors. If the cash is depreciated but the economy doesn't completely collapse, then if you purchased stocks in a company, assuming that company continues to exist and is still viable, it may retain its value. You have to keep in mind that some companies may weather high inflation better than others. You'd have do your own research on that and even then, there are no guarantees (law of unintended consequence could boost some stocks and collapse others, and these are not easy to predict). On the other hand, if society completely collapses, all bets are off. Depending on the type of collapse and what institutions survive, no one can say what will retain value (Except perhaps for emergency food rations, the ones that don't go bad for a long time. Economic collapses inevitably create food shortages so food will have value as long as it doesn't spoil.).
Physical gold and silver is probably a good bet if you can get it at a good price. However, there is 1 catch for these items. Corrupt governments have historically stolen gold and silver from people when they took power. They did exactly this during the Russian revolution when they needed money. If you do acquire physical gold or silver, hide it well and the less people know about it, the better.
