but still after 1 or 2 years i told it - horizen has no marketing... Horizen never will be succesfull until marketing will be one of the most important thing.
You don't learn anything...
This is not true, it depends from what perspective you are watching. Currently whatever you do on market won't have some significant influence on price while Bitcoin doing its Ups and Downs.You don't learn anything...
This situation is in the whole Crypto. What are your suggestions? What should be changed?
You even lost power which you had from Palm Beach Research recommendation... and still you don't learn anything 
What power? They played their games as they are doing with all other projects. After 51% on Horizen network - > https://blog.horizen.global/zencash-statement-on-double-spend-attack/ they did and nice dump casued with wrong and inacurete statements at that time. So lets forget those pumpers groups, no real value behind! You always has answer/explanation... why horizen stands in place
There were many chances to move this project to next level, make it more popular, more fameuos, be in top30-50 on coinmarket... Since few years you can't move stabilly to top100 on coinmarket - why? Because there is no marketing, never was and still nothing changed and learned. I suggested many times what you should do in many areas (marketing), i even wanted help (not now)... but i think you don;t see value in marketing, thats why horizen isn;t succesfull. It was good, such attitude 20 years ago, now almost everything is based on marketing, "selling ideas and plans" to people...Because of PBR, their authority zencash then price move from $8-10 to more then $20-25 and many people because of them saw in this project value, future. This situation you also didn;t want to use to promote this project even more.
If you want to make something good to this project - hire somebody smart (marketing guru) who can make horizen popular (there is many ways to do it)
