Get FreeWallet desktop version and explore it..
Lots of volume, people find them by viewing available dispensers, I consider current market rate as lowest price dispenser sell (give 1), you can also do it on wallet.counterwallet.io , atleast their is an option for creating dispensers there but I have not used it for dispensers..
FreeWallet works great
Thanks a lot, I will do some testing.
BTW, do you know what happens if a dispenser shows as available, but gets emptied right before you send some BTC to it? Can the BTC potentially be lost?
