Transaction fees are 0, at the moment we had to rise it for 1 leaf ( 0.0001BMB ) to secure the network in case someone would flood the network with fake transactions. This transaction fee will be taken again out after we will secure the network against such behavior. Just a small information: 0.0001 is the max decimal, we dont have more decimal numbers like other coins out there. What are the advantages? Well each one should read our whitepaper to understand our tech. In short, we dont promise any best latest updates and improvements. We would like to be interesting and easy to use for people. That is why our code is also lightweight in compare to other coins out there.
