The market changed how?
Bitcoins are not any less useful this week.
Exactly. Bitcoins did not change. THE MARKET changed.
The technology underlying the asset does not affect the emotions of traders. We are now in a bear market, which means the trend is DOWN. If someone disagrees with this, I would like to hear what exactly changed between April 15 and today that is getting people so pumped again. I can't see any reasons other than short-term memory and greed.
Media coverage, new stores accepting BTC everyday, news about infrastructure being upgraded, plans on opening proffesional exchange in London etc.
