So money through a token sale can be classified as an operating activity and not a finance activity.
once the project is launched and operating, the token is not a token anymore. Like you say you can purchase the product/service using the tokens (you purchase some coins). But it is because the tokens have been converted into the altcoin
You lent money to the project and the project promise you to send it back in the form of tokens (crowdlending). Then you are supposed to cash out your initial investment and you're done. The fact that you speculate with the tokens is something else.
If you notice their websites never promise, you will make 120%-150% ROI and so on. At least I have never seen it so far
if the tokens can be used to purchase a product the tokens shall have a fixed value.
Thank you so much for your insights. It did bring a different point of view.
