I don't think we will see any of that happen. Dollar is strong. Once it falls back, some inflation will take and stocks will continue to rise, not all stocks though. Just ones that are needed. Sky will not fall and humanity will continue to advance under the close eyes of corrupted officials and the like. The only thing in danger here is nature, good health and freedom.
Do your DD! Spend only the money you can afford to lose, while still willing to play at other tables. Commissions are cheaper than losses!
