I do agree with it's different this time.  People will wonder what exactly is the purpose of bitcoin.  Is it a get rich quick.  No.  Is it a store of value.  No because it's too volatile.  Is it a currency.  Not really because it isn't accepted in enough places.  In fact hardly anywhere.  This could all change of course.  But people should ask themselves these questions instead of blindly following these calls buy buy buy or sell sell sell.  Why do they want to put their money into bitcoin.
