IMPORTANT: Invalid blocks and Bitcoin wallet upgrade
07/05/2015 by LakeBTC.com
There's a planned bitcoin system-wide upgrade but some miners still generated invalid blocks.
Bitcoins confirmed before 2015-7-4 15:00 UTC are reliable.
For bitcoins received after than time and if you use certain software, the confirmations are significantly less reliable. Please see this post for more information.
Or, you may use a professional bitcoin wallet service such as LakeBTC's and do not have to worry about all the technical details, safeguarding your environment, or software upgrades.
