From the news section of Bleeping Computer a few days ago . This relates to a motion before the US Federal Court of Northern California to force Coinbase to disclose the personal details of all US users that have conducted Bitcoin trades between January 1, 2013, and December 31, 2015. Granted , it is in a specific jurisdiction , it only directly relates to Bitcoin trades by US citizens , and in a given time-frame . But it is an indication of the way the wind is blowing , and I find it surprising that it has attracted so little attention. Perhaps Bitcoin has out-lived it's usefulness and should be put to sleep , in a humane fashion . I doubt that this scenario could occur if zcash became the de facto crypto-currency .
