One can sell his goods or services today and deliver them later. It's like a forward contract, for example: to crowdfund real estate construction at the early stages (day-usage-tokens instead of square meters), agricultural businesses to crowdfund their harvesting (potato-tokens), for air tickets or tours presales. Profitable for investors: significant discounts, or re-selling tokens at the exchange for profit. Profitable for manufacturers: make money today, make turnover faster, promote his own goods and services, payments with his own goods and services. This is a foundation for the barter economy like Swiss WIR.
