I think this coin has a lot of potential and is underrated. If they do half of what they promise, it will be a big deal.

I agree. Arc is way the most stable nodes I have. They run without any issue, never crash or expire. Easiest to deal with.... The biggest issue is the communication from the team. No regular communication from the devs, nor between community members. The slack channel has 1 message in every 2 days. Usually just asking if anyone is there.
The tech is stable, the wallet is solid... But the communication and marketing? Need a huge improvement.
