In fact, with being publishing of DAP and other blockchain technologies, cryptocurrency may be possible faded out from the stage.
name 1 good DAP that has actually done something and explain what that something was. if you can show us a real world application of DAP not just what they promised to do but what they actually did, then you are correct.
but the problem is you can not do that because so far all of them have been ICOs to raise money not to actually do anything. they promise to do this and that and solve a lot of different things but in the end when it comes to reality you can see they did absolutely nothing. they just got paid to release a token for trading on exchanges. and that ends there!
