IMO 2020 and first half of 2021 can be worst in terms of economy all over the world and more or less , every one has been affected from Covid-19, But our focus should on "avoid-depression" and keep your self as supportive as you can for your family, fellows and every one in your contact. This is not the period when one should think about more savings but utilizing your existing savings on your loved ones. There is no replacment of life and health. (sorry for my poor language), Yes its a little better to reduce some "fazool-kharchi" but do not cause it stress for your family and loved ones,
There is no hard and fast rule that either GOLD will increase always or USD will increase.
USD value always depends on balance of payments. so keep look on schedules that for the period when govt have to repay some big loan installment, USD will increase and when govt will get some liquidity from IMF/ADB etc,, USD will become stable. other currencies like euro/pound are more risky and these values fluctuate more often than USD. so chance of more risk, more gain, more loss depending on holding power.
I see no truth in rumors of alternative global currency against USD , no matter trump stays or not after 2020.
Also if you are newbie, please stay away from digital currency like bitcoin
