Here is 4-hour Cub Price chart. Cub price was going down day by day...
It was stable around 0.50 USD about 6 days in rectangular area at chart.
Someone in this area may have collected CUB at low price...
and Volume and price started to rise...
hope to see more...

I dont know what happened.
It was definitely a surprise that CUB came back to 0.75. Don't know WTH happened though.
