Picoin is free mining, and it is the first coin to be mined with a smartphone.
Intra mainnet was opened in December 21st with a coin developed by Dr. Nicholas Stanford, a former startX CTO (technical general). Up to 100 million people around the world are expected to be mined (currently 60 million people)... Products can be traded on the intra mainnet, and listed on the exchange during the open main net (expected in June 2024). There is no harm in having it, and many people are mining it because it is called the second Bitcoin mined with mobile phones.
