Is Reselling World Cup Tickets Above Face Value Halakhically Permitted?

QUESTION

Riverdale, NY

Employer’s Delayed Payment of Bitcoin to Employee

January 9th, 2023|Business Ethics, Choshen Mishpat, Interpersonal Ethics|

QUESTION

Philadelphia

Kvod HaRav Linzer:

An Israeli man was hired to do some contract work, and the agreement was that the final month ‘s work would be paid in Bitcoin. The employer never paid that month’s salary, despite the employee repeatedly asking to be repaid. Finally, over 5 years later, the employee received the payment of 3 bitcoins. The sum is worth much more than when it was to be originally paid, but the employee lost the opportunity to potentially sell when the price was much higher. What does the employer owe now as fair recompense? Thank you.
