If you put a longterm trade with a near 100% chance of success, it sure is better than short term trades with maybe 60% chance of success.
Examples, everyone knew the brexit would weaken GBP, you could easily put a 1300 pip or so even after the result came in(!), the french election weakening the euro, here you could make about 700 pip with a poor entry. The US rate hike path, where you could make 2000 pips in a few months on several major pairs. The political situation in greece last year, the political situation in Turkey, the situation in Brazil, in Russia, the move to normalization on the JPY etc etc.
