Hello,
Why you think you can handle such a big project? and How?
Why you chose Ethereum platform if you need a lot transactions per second, and there's better platforms than Ethereum, such as NEO, Waves, QTUM .. ? How you choosed platform what did you look into?
How aware are you with technical limitations? How would you solve those?
Why you think it will succeed?
Why you think people need it and would adopt it?
What problem does it solves?
If you're launching your own blockchain, than how you're securing it, which consensus, and why you think it's best solution and why not to use some existing platform?

Thank you.
