Minimum 500k was removed after nabi stopped supporting Paypal scams and stuff.
Current rate of TC/$ is going down which = more money for you.

Its true, the current rate is around 10k per dollar. Many buy for a higher rate of 11.5k per dollar and sell at 10k per dollar or lower. You can sell regardless how much tc you have, you can not make a thread without 500k. Tc sales are unsupported by nabi so when buying and selling be careful, since offenders will only be banned(permanently) but if they get off with your money they wont really care.
