it is not easy to hold pCub when the price it is only going down.

Oh, I agree with you on this! It is not easy, but it's the same with any other project out there... If you have trust (and maybe some insider information 😃), you can "easier" push through this period, but always, in the end, those who were "diamond hands" in hard times, get the biggest reward... If the thing evolves in the right direction...

I think if we wnat more users interested to stake in polycub it is necessary have a better APR and a better token price.

This is also true, but there are many things connected with the APR calculation... If the price of Polycubs goes up, the APR will also go up as it's calculated in USD...
