Based on Coinmarketcap, the last data recorded of Bitboost trading in May, even though I had waited almost 6 months but this token still had a very low trading volume
What's wrong with this platform? Is it a scam, because I don't see the seriousness in developing this project

It was remove in coinmarketcap due to low trading volume, I cannot comment about scam because I have not seen any evidence that will prove.
One major problem I saw is that their lack of marketing and decent exchange, if people will see liquidity, we will still surely see this trading live until now.
