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.
I actually Laugh at your reply to him bro hahaha!. You are right holding shitcoins will make you stupid and shit
Before holding a coins or a token make sure that it have a good potential and have a good future you can easily notice that about what is the project of an ICO about their white paper so if I we're you Im gonna sell that shitcoins that you are holding 3years and 5 years because you will have no future with that
