kudos for taking advantage of the situation and swooping in with lightning speed

.
but a word of advice, you will make a lot more money if you make an altcoin like this from scratch instead of forking bitcoin like this. you can still fork the code and not use the 150 GB blockchain. that makes everything easier and testing and syncing and everything is much easier. you also don't have to worry about replay protection and not worrying about the dumps that will come.
your premiend coins will be worth nothing by the time you get around to dumping them. you can look at what happened to bitcoin gold and it is not even released yet.
