My favorite BM at the moment is Hhampuz. He does a really good job and is usually very reliable. So far I was involved in two signature and a reddit bounty campaign and each time the bountys went without problems or similar. Therefore i am more than satisfied with him and can only recommend him as a BM. Who wants to reach Hhampuz, will find all information about him here. https://bitcointalk.org/index.php?topic=4873710.0
