I think Robosats is available! its just that there isnt enough market on it locally so I prefer a face-to-face P2P (all underground but there is a big market mainly buying/selling USDT by Merchants

Merchants is a new profession emerged to fill a gap (banking on/offramps), they buy USDT from people at 1$ and sell it to people for a small premium (anything from 0.5-2% premium depending on demand)
