Later, I bought Homeless and Immigrants cards and did training. The high-value cards obtained after completing the training are also sold in the marketplace.
But in the market Immigrant card is expensive than Worker, Scientist and Artist card. So if you buy Immigrant and got Worker, Scientist, or Artist card. It is total loss and waste of time and energy. Homeless card price is also almost equal to Worker, Scientist and Artist card.
That why its not easy that we think. But We need to consider about card effective. Mostly I am buying homeless card.
