Exactly.It does make no sense to make mining of a new coin this difficult at all.In fact most coins when coming out they are starting with a very low difficulty so people can have a look at that type of coin and see if they like it,if not they get away.
You OP by doing this,adding without any logic of algorithms you just make it burdensome to mine this type of coin and most people will be turning away from your project,not that there are many profitable projects nowadays in mining anyway but why turn people away since the early beginning?
Don't make me just follow the path, I'm making my own trail. If it make no sense, why canxium network reach 1 TH difficulty just one month after launched, why miners around the world are mining it now?
Don't be silly. Take the risk, or lose the chance.
