With almost every coin, and probably every algo out there, there is one enormous problem: the distribution. Most coins use PoW. It's biggest flaw is that the more Hashpower you have, the bigger your reward will be. This should not be happening. The amount of coin a node should be able to gain should not depend on that node's hashpower, and it should be limited for the given unit of time. This will ensure a fair distribution and will also make the development of dedicated mining equipment superfluous. Solo mining will be encouraged and more and more people will come to claim their fair share, thus helping secure the network. There will be no pools, no huge farms and no useless dedicated hardware. People will mine using their phones, laptops, PCs, and will do this while enjoying other activities on their devices. There will be no need for specialized software, because mining with the wallet will be sufficient. This will be the future, and that future is not far away.
