I can not estimate the real potential of this.
About the potential - these are the markets LATtoken are already working with.
EQUITY (global asset value - 65 trillion$) - Listing equity on a stock exchange is a very costly process. Underwriters and bookrunners syndicate fees are ranging from 2% to over 6%1 of gross proceeds from the offering, application and filing fees fee average around $25k.
DEBT (g.a.v - 215 trillion$) - Issuing debt on a leading stock exchange incurs initial listing fees of ~$20,000 and an annual fee of ~$20,0004 . Underwriting fees generally amount over 1% of total gross proceeds from debt issuance.
REAL ESTATE (g.a.v - 217 trillion$) - On average home sellers pay their listing agent a commission of about 6% of the price. Other transaction costs amount to ~5% and include escrow costs and recording costs upon sale, title insurance costs. The sale process takes on average not less than 65 days. The proceeds from the real estate sale are taxed at the rate of up to 20% .
ART WORKS (g.a.v - 3 trillion$) - As per example below seller fees associated with an artwork sale are 20-25% of the sale price (hummer price) while buyers premium charged up to 25% (according to Sothebys commission structure).
LAT can greatly reduce all these costs. This alone already has really huge potential.
