Initially the coffee machine looked not bad but if you do a further analysis u will discover it's not worth it.
To invest the 10 coffee machines that gives u 20% return sounds promising without taking into account of the depreciation of the coffee machines.

If you buy a new coffee machine, what will you expect for the price for the coffee machine after 1 year, 2 years or even 5 years? The best case of the return for 5 years just enough to cover the coffee machine price. Most likely after 5 years, the coffee machine is worthless. I wondered if the users still want to rent an old coffee machine than a new one.

There are lot of uncertainties regarding the price of license too whether you can transfer it with a premium or discount. I wonder who will be stupid enough to buy your old coffee machine.

All in all, the investment scheme is only good for the company where they don't need to fork out money to invest in the coffee machine and at the same time they can make money by selling you the coffee machines and rented it out to users to earn the capsule price. I would rather be the user than investor.

it's similar buying a new car and rent it to other people. The company gives u 20% annual return but after 5 years ur car is worth much more lesser... The net return might be not different to your fixed deposit with much higher risk where the company might be out of business after 5 years
