DOGE annual inflation of 5% would not be such problem if it was not mined far too quickly.It was good for quick buck speculators but it devastated coin on longterm.

DOGE has some advantages in regard of number of processed transactions per hour,cheap transactions and if mining process was setup to last as it was for BTC,DOGE destiny would be far different.At least it would be in position which DGB has now,which took all the best from DOGE and eliminated the worst.

DOGE price in BTCs is bouncing in same range for years,unlike some others big coins.When you look at possesion structure you can see how DOGE was far more centralized than others so call big coins.It means that handful of people was able to grab majority of coins at very cheap price due to massive and very quick mining process and effectively took full control of coin,which gave them power to complete control price and pump/dump at will.

Even if some other players with a lot of money would like to overtake DOGE,they cant,because they can buy only about  5% of total supply on exchanges,far from enough to change DOGE fate.So,Iam very sceptical about DOGE future,unless today majority owner/s make deal with some other big players with greater plans to coin than just pump&dump and sell them coins off exchange.But it is highly unlikely.
