Hey guys! I've just seen 2 tweets from 23 jan. made by Alex Bosworth where this guy could finaly buy a cup of coffee for bitcoins with a low fee fast transaction. It seems like the lightning network is successfully tested in the main net and soon we can expect to hear more details about its launch. Brace yourselves, better times are coming

very happy to hear this good news. I do expect a lot on this blockchain technology. I'm not satisfied if bitcoin is only used as an investment asset, but I want bitcoin really legal and can be used to transact around the world.Tweets:
