I've used it to sell bitcoins. It's quite safe provided you are careful and go for a buyer/seller with a high trust rating.
Been there since past 7 years and no issues at all. They are completely safe and great.
I mean people could just use coinbase/binance, etc or cashapp things like that for cheap BTC, theyre using LocalBTC to avoid something i imagine most times, no? Hence the higher markupI've used LB before to buy different crypto currencies. It's good overall, but the prices are so darn high (especially when buying from trusted sellers with good reviews).
