According to the latest wallet release, the least maturation period for Buzz coin to stake right now is 5.6 days (that is if you updated your wallet to version 3.1). They provided a well-detailed information about it in their website and you should check it out. Also, make sure that you have the 3.1 wallet running before the 950k block so that you will not have any problem moving forward. Join their discord channel if you have the app for it and see for yourself what they are currently discussing there.
