I also think so. I did not recieve my airdrop tokens!
Its not a scam for sure, but unfortunately their marketing side has been the worst i have seen. They have a large following in asia already but they have not focused on community engagement and social media avenues in the west like medium articles, reddit e.t.c, the actual project itself is far more advanced then every other supply chain token out there including wabi, Ven , walton chain, with their RFID chips linked via 5G network for real time live tracking and record on the blockchain. Their chips are already in production. The team is probably the most experienced as well. Join their telegram channel

The project is completely under the radar in the west, hopefully the team starts to market this better as right now it is very bad. This is potentially the best supply chain project out there and yet hardly anyone knows about it!
