The DePIN project @ weRoamxyz, which I am most optimistic about, has recently come up with a new concept of tokenizing mobile data into assets. This can be understood as: if I go abroad to buy 20GB of global data and only use 15G, the remaining 5G is usually "given" to the operator by default. However, Roam has now changed its mechanism, which allows me to "sell" the remaining 5G back to the operator and turn it back into money. This change may completely overturn traditional communication restrictions. Roam's deep cultivation in communication is becoming increasingly interesting. Not only does it launch never expiring data packets, but it can also exchange data for ROAM or other currencies. With Solana's low-cost and high-speed support, transaction efficiency is extremely high. In addition, the most basic aspect of DePIN is hardware, and I have been holding ROAM for a long time. Recently, I have been considering Roam's WiFi mining machine. Based on the current mining machine production capacity and ROAM price, it may not match well, so I will keep an eye on whether there will be any updates on mining machine gameplay in the future.
