Do you want to be a trillionaire. Yes it's possible by spending only $ 100. The exchange rate in Indonesia is $ 100 = rp 1329361.90 as of 25th March 2017. Though it might not really buy you what you think a trillion can it took care of our one day stay and food.
I had a trillion when I entered the country and I thought that would buy me a world but because the prices of smallest things are in thousands eg, coconut water for rp 30,000.00 I could survive for only one day including meals and accommodation in a trillion.
Every country is a whole new different world and I learnt to never compare any two different places ..
Please do not mind the most commonly available souvenirs of Bintan !!!
