there were 2 attempts these last days to pump this coin but nothing happened. I think people lost interest in this coin

It is quite the opposite. More people are now taking a serious look at CLD. There has been quite a bit of accumulation sub 30,000.
There are a few key facts you are forgetting.
1. It has only been 8 days since CLD started trading.
2. CLD is 3x the ICO price, compare that with Syscoin.
3. More people are starting to remove their coins off the exchange & staking. This is a clear sign more people are holding long term.
4. The dev received the ICO funds and still here working on the project. It is clear he is putting the funds to good use.
So the key now is just to have patience and allow the dev to keep rolling out new features and services.
