in theory we could start the business with 1btc but obviously it would slow the growth progress and increase timescale drastically. I don't think the whole 60btc will sell we just provided the option incase it was a massive hit. Also if coins dont sell the price will go up as there is less supply so investors will have automatic profit. ideally for us to successfully start the business off we need 10btc and anything greater will be fantastic and give us more options for the future and to do everything quicker
