I was trying to do a form% speedrun. But realized it wad taking a bit long, so can someone give me some tips for form%? Any tips would be helpful

Best way is to use a lot of trades, specifically buying at 80 and selling for 100 to quickly increase coins. Though how long you trade in the early game is dependent on the form.

If you're going for a long form%, the fastest way to get a lot of coins is trade until you get to 26,000+, then take two small countries, expand your supply ship capacity to 1000, do the 10 coin good trade deal (always happens after conquering your second country) and sell to get 100,000 coins. Keep conquering until you can do the 20 coin deal, then the 50. This is the best way to keep coins high while you complete the form. try to sell during longer attacks as well (keeping coins high)
