The odds of getting delisted from all exchanges is nearly zero. Cryptsy's policy is that they will not delist any coin as long as the blockchain is running smoothly. There are coins on Cryptsy which have had zero volume for months and with no active development yet they have not been delisted.
That said, to start your own real exchange and have it be professional, fast and secure would probably cost ~$100,000. That's a ridiculous and unnecessary cost at this point.
Use the limited funds for necessary things and let's put off anything which can wait simply because Bitcoin will be worth much more in the coming months. Let's not waste those 400 Bitcoins at $350 when they're likely to be worth 10+ times that in a few short months.
Imagine having well over $1 million as a development fund. That's enough to turn CraigsCoin into a top grade alt-coin.
