Definitely don't invest any money into a new coin unless you think it has a good reason to exist. If its simply a copy of another coin with one or two settings changed, then its most likely a "scam" coin which will most likely never have any value in the long run.

If you wanna 'get rich from launching a coin', then implement a new feature and innovate, if you have enough knowledge to launch a coin, spend just a little more time to try and do something new/different. At this point all the copy cats have had their day if you ask me, I don't think we will see too many more 'junk coins' take off in the near future.
