The simplest way to earn is to trade. The best way to earn at the moment is to invest in good projects early on. When you invest during the pre-sale stage of an ICO, initial coin offering, you get a good discount, which allows you to earn more when the coin is released. One can also participate in what’s called an “Airdrop,” in which one may receive some tokens in exchange for sharing content or campaigns during the ICO.
Other ways to earn is to place a Bitcoin or cryptocurrency teller on your business property. A change kiosk/shop can actually facilitate cryptocurrency exchange transactions from a tablet.
