For anyone that didn't already know Bitcoin will be doing a split as of July 31,2017. So half of the nodes will but running software that is not compatible with the current which will result in some nodes propagating confirmed results and that other won't recognize.

Basically, any btc received or sent after may get to its destination or it may not, and on the chance it does make it to the correct address it may disappear which means you lose money even when buying from atms or reliable sources.

This form of payment has become a big part of this community and when a source shared this with me I figured everyone should known if they didn't already. So spend them if you have them or put them in cold storage or on a flash drive or something else to keep your money safe.
