Because your coins is bullshit too,that is why there are no improvements,HOLDING good altcoins and tokens will give you a lot of profits but holding these shitcoins which doesnt have good working product/services wont give you anything even you waited hundreds of years.Do a lot of research find new potential coins or projects only invest to good projects,read whitepaper check the team,the current developments and im sure your holdings will give you much better outcome.
That's right. Funny but true. it depends on the coins your holding, it will surely be useless if you would be putting your faith on those coins that would mature to be good ones in the end. If that happens, then you can consider you venture of holding them as in vain because they won't give you any profit that is worth the time you have held and kept them. For some people, they don't think that the amount of earnings they should get should be considered with the time they help the coin for, to me, if you only gain around 10% after holding it for a year, although that's profit, it is still a loss in my column.
