Not everything I wanted to know about ICOs. Every article I've read is from the speculator perspective, perhaps for potential speculators. I am more interested in knowing about ICOs from the organizational perspective: After completion of the ICO, how are the crypto-currencies converted to cash in the bank, so you can put the capital to work. Is there percentage loss of capital when converting to cash, and is this accounted for in the ICO model. Does converting 10 to 50 million in crypto-currency to cash cause fluctuations in the market value of the crypto-currency. The project may require resources that only can be purchased with fiat currency. And I assume people working on the project have bills to pay. Has anyone documented how an organization deals with the crypto-currency that as been raised via a token sale? I suspect that each organization has their own method of converting crypto-currency to working capital.
