Why not rename it Fappycoin ? You know its catchy.
We are seriously discussing rename, however if we give up the name, it would be a bit like admitting defeat to these thiefs/scamers. They are unethical people with a very dubious morality and we do not want to "reward" them in any way.
Look at it like an iteration, not defeat. I believe you are right in considering a rename.
If you don't rename your coin, your efforts in promotion may lead people to the pools of the 'other' Flappycoin and you will lose support. I applaud your tenacity in holding true to your vision but the truth is that "first movers" normally have and try to keep the upper hand and market share.
I suggest you use this hype to get your team together and use this as launch pad for a newly named coin.
Best of luck!
