Imagine it as a bet with a friend.
You: "hey, I got this item worth 10 but I believe it will go down in the next five days."
Friend: "no way."
"want to bet? You will buy it from me for 10 whenever I want to sell it."
"nah."
"I will give you 2 to keep right now!"
"alright."
Your friend has no say when or if you sell. He got paid and hopes you are wrong. Your friend will obviously not agree to pay 10 for an item that is already only worth 5. And yes if the item only goes down to 9 you lost 1 on the bet.
No, I'm going to argue that you gained more through possessing the device than by having the money you spent.
Unless your stance is that only money is wealth.
It's true that a sharp knife feels great, but they said 'blunder' for a reason.
A sharp knife will leave a clean cut on meat and not squish vegetables, but the question is if the average home cook cares enough about slightly squished vegs that he had to push through more than slice or a feathered meat cut when their goal is to put dinner on the table.
