How does Celsius Network make money?

Could you please elaborate on the revenue streams of Celsius Network? As a cryptocurrency platform, I'm curious to know how they generate profits. Do they primarily rely on transaction fees, interest rates from lending services, or perhaps a combination of both? Also, do they have any other sources of income that contribute significantly to their overall profitability? I'm interested in understanding the business model behind Celsius Network and how it allows them to stay competitive in the market.
