Interesting subject. For example, the inflation in my country (venezuela) is so high (google it) that is actually better to receive weekly pays and buy everything you're going to consume as soon as posible because the prices rise constantly and faster than the salaries. It's an economy in crisis. That's why my compatriot steemians have the habit of cashing out their sbd asap. The sad thing is that steemians from countries with a more stable economy do the same mistake.
