I would suggest buying bitbean only from bittrex because bittrex is reputable exchange and we need more buy support to make bitbean stronger
That's where I normally buy and have bought all my BitBeans but like I said I had to transfer some other coins off POSWallet as they were delisting them and the only exchange that accepted these coins was Yobit. So I sold them all and I made sure to check the BitBean wallet on Yobit was online which it was before I bought BitBeans. I then made the withdrawal and now it is stuck and we all know how poor their support service is so I guess I'll be waiting for weeks before it is fixed.
