Hacker and Entrepreneur! how will he turn out 5 years from now? and carousell is becoming our own localized NC(16) version of the silk road.

an NTU student at the time, hacked four Kopitiam cards more than 130 times, and used the ill-gotten credit to top-up more than 180 Singtel pre-paid SIM cards in exchange for cash
He began his hacking spree in 2015, while pursuing a computer engineering degree at NTU.
While staying at the hostel, he researched how to hack stored value cards for free air-conditioning.
Around August that year, he realised he could also modify Kopitiam cards to get food and cigarettes for free.
He would change the last four digits of the hacked cards to avoid detection.
He soon discovered he could use the hacked cards to top-up Singtel pre-paid SIM cards.
Tee saw this as a business opportunity and began offering discounted top-ups through online marketplace Carousell.
As an example, he would charge others $8 to top-up $10 in their Singtel cards.
He received about $34,000 from Carousell users this way.
