So its only btcpop that you can buy/sell beancash now?
You can also get beancash on stakecube and some others.
StakeCube has been a great way for me to accumulate more beans as I also stake other coins on there and have been using the stakes I earn to buy beans each week and I just leave them on there to stake. So far I have just over 70k beans on there staking all purchased from stakes I earn from other coins.
