When looking for a project, especially with an ICO, people are you usually looking for a specific service provided by the project such as, well, betting. If a new project comes along and offers something new, the old project will react to it and take steps to get people back. In terms of going all-in from the get-go, imagine if Apple introduced the perfect smartphone back in 2007. What would they be selling right now?
I don't think that it is 100% correct to compare cryptobetting and Apple, as betting via cryptos is a very new and fresh field, which requires an approach different that one that a huge corporation like Apple should use.
