There are many options to choose from depending on whether you can manage it or not. The amount of $30K USD is a lot in my opinion, you can use it to buy good coins like Bitcoin, Ethereum, BNB or Matic. With a bear market like this, if you want to get maximum profit, it will be very difficult. But if you want to trade long term it is the wisest choice. So think carefully before you act, because the possibility of loss is still there if it is at the wrong time.
