Little investments only make sense to people that have a low amount of money. Those people that have much higher income, it would be better for them regardless of the result, they wouldn't feel satisfied at all because the money wouldn't have any notable influence on them financially. Funding is the reason why you should go big when you are serious with your investments. Go big or go home that's my motto.
Go big or go home,By the way It's a great sentences. I think small investments make sense for people who are new in this domain. They should begin with small amount to make some experience. After this step, when investors had a good knowledge about this domain, they can start to increase their investement.
