Everyone/project come with a hope of competing with bitcoin, forgetting the it took year for bitcoin to get to where it is now. Moreover many privacy coins has been release yet most people still sticks to the pioneer coin.
From my own point of view this coins has founder and can be brought down anytime unlike bitcoin that remains anonymous.
Grin drop drastically in price few days into market I hope the future has a better out come for the coin.
In my opinion bitcoin will always be number one. I just believe healthy competition is good for the crypto community and Grin is doing just that. Only time will tell if it will be successful.
