If you read it, mine was a question. If you have any special knowledge, Enlighten us please.... If you have to use centralized third parties to use it efficiently, then it defeats its purpose. my single bitcoin remained there, because I couldn't use it in an easy manner. I am kind of glad about it, as it has risen in value, but really, apart 'it rises in value', what practical use does it have? Feels like modern day tulip mania.
