Since Polycub was first released, I've tried several times to buy CUB, so far nothing has worked.
I went back and forth to open Hive Engine to make transactions, it turned out that there was a change in the User Interface on Hive Engine, the display is now more attractive and neat, unlike the previous version which often lags.
Speaking of CUB, I've tried three times to buy CUB with LEO that didn't work, or at least I don't think it worked because I didn't know where my LEO was headed.
First I sent 5 LEOs to p-leo, then twice to b-leo and also p-leo, 2 LEOs each, so a total of 9 LEOs that I have tried to send.
I still don't have CUB. I don't know where the error is, so I tried to dig deeper and found a post from 
It turns out that I have to import tokens first so they can appear on Metamask by adding a token contract address, be it CUB, bLeo and also pLeo. Now I can see the number of bLeo in my Metamask wallet.
The next step is to buy CUB on Leodex, I didn't find CUB on Hive Engine, there is SWAP.CUB, so I decided to buy CUB on Leodex according to the number of Leo and Hive I have.
It turned out that an error occurred in my transaction, I'm still in step by step following the guidelines from the article above, I'll try to find out where the error I made.
With days running down to get airdrops, and I still haven't managed to buy CUB, maybe any suggestions I can follow? But despite all that, at least I learned something new in my process of buying CUB.
What I have done has given me a new experience and a new perspective on LEO and the projects they have built. Maybe tomorrow I'll try again.
