If we can really achieve 1 MLN of tx/sec there won't be any competitor in the short run. But as of now it's everything theoretical. Even NANO (former Raiblocks) can scale up to 7000 tps, but... the stress test didn't reach such numbers. For now the top tested was around 306, here is the link showing it:

Hope my answer will be useful for the following discussion.
Now this is why -also- bitcoin is hard to hack. It will take time and cost so much money. Isnt lightning like creating a warp hole. Gathering user there and creating the transaction before writing in the block chain? So that warp whole can accomodate thousands of transaction, right?
