It will take more cards to level up later levels. Usually, when you level up someone from level one and give them a high ranking level 2 or even 3 card, they will level up almost 20 levels.

Also, keep in mind that during events, players get a bonus multiplier to both transcanning and selling cards. On the last day of the Robots in the Sky event, the bonus was x3!
