I think best change will prefer you using an address starting with 1 or 3.
Valuable comment, but now we can work with bcq1 addresses as well, so feel free to use these addresses.
Does this apply to all participants in the Best_Change signature campaign? New members can immediately indicate bitcoin address in the format bcq1, this is understandable. Is it possible for old members to change their btc-address to bcq1 format? If so, what information should be provided for this? In this thread or in a private message? Specify the details please.
