https://bitcointalk.org/index.php?topic=1204912.0The day's of making a altcoin and making money are pretty much over unless you bring something new to table. There were a lot of pump/dump coins that never went anywhere.
If you just change name and image of coin... there will be a few that mine it at launch but I don't see it getting on a decent exchange or holding much of a value.
There are too many altcoins nowadays. Almost every single one is pump and dump and gone.
If you really want to develop an altcoin use one that's out there, there are thousands of failed ones

And a lot of them are utter crap. The owner of the coin can pre-mine and claim it's for rewards down the road. It is crazy some mess with some of these altcoins.
If it does not have a time/date to start mining and it does come pre-mined, there is pretty much 0 percent it is accepted long term.
