After mainnet, IOTX value doesn't change much and I'm quite worried about this investment because really everything in this project is very good but the price increase doesn't happen at this coin. I held a large amount of IOTX in May and until now, I have not made much profit from long-term investment. Hopefully in the near future the group has many smart strategies to improve this issue because I am a loyal investor in this big project.
