Come on. The 1800s „recessions“ were minuscule at worst compared to today‘s global meltdowns happening every decade. Think about the Asian crisis of the 1990s, the New Economy bubble burst at the beginning of the 2000s, the sub prime crisis 12 years ago and now a post Covid recession.

Also you‘re taking one feature „they had a gold standard back then“ and take it as the single point failure. In reality having a „Gold Standard“ does not guarantee a non-inflating currency. In the 1920s the FED was printing more dollars than were backed by gold to pay back the government’s war time debts. The same happened in the losing nations like e.g. Germany, too, in a much greater force causing a death spiral completely destroying the German Reichsmark. In the US you were lucky to just experience a stock market boom that spectacularly burst in 1929. This would have caused a recession for sure. However, the decade long depression that actually followed was a result of unprecedented economic meddling by the federal government under Hoover and then Roosevelt.

The Gold Standard was removed after the „Bretton-Woods“ system broke down in 1971. That was an attempt at establishing an international currency system with fixed exchange rates. It worked in a pyramidal fashion: The US promised to have their Dollars backed by gold and the middle power nations‘ central banks backed their currencies with US dollars. Of course, the US printed more dollars than they actually could back by their gold reserves. At some point France demanded to redeem their dollar reserves in Gold. The US did not comply and in 1971 Nixon declared the Dollar not being redeemable into Gold any more because the FED didn’t have enough gold left. Since then the US dollar as well as all international currencies are backed only by the people’s trust in them and by the fact you have to pay your taxes in those currencies.

So you see the monetary history is primarily a history of failure induced by bad economic policies. How currencies were implemented is just of secondary interest.

Bitcoin could easily serve as an international currency compared to the US dollar. Its value is based on trust like the US dollar. Governments could collect their taxes in the form of bitcoin if their wanted to without a major systemic change. And unlike the Dollar or Euro, Bitcoin couldn’t be inflated. Whether that will happen and change economy for the better is still left to be seen.
