Forget Bitcoin ... Kevin Durant's Nets debut jersey could be the next hottest thing in the investment game -- it just hit the memorabilia stock market, and it could net ya a small fortune down the road!
Here's the deal ... the threads KD rocked in his first-ever game as a Net on Dec. 22, 2020 just hit the investment app Otis, and fans can now purchase shares of the uni for $10 apiece.
Reps for the app tell TMZ Sports once all of the initial shares are sold ... it'll go up for trading, and the owners who bought in can hold onto the shares or sell them -- just like a stock.
The current value of the jersey is estimated to be $47,600 ... but experts say it could go up way higher in just a matter of weeks.
After all, Durant's debut with the Nets was a special one ... he put up 22 points in a victory over his former Warriors squad -- and if he's able to win a ring with Brooklyn this summer, the uniform's worth could obviously skyrocket.
In fact, reps for Otis say it's not uncommon to see a 150% to 400% increase on pieces like these.
Selling of initial shares on the jersey began Tuesday ... happy trading!!!
