price volatility, complexity, PR, worldwide bans, strangers around, relation to black market/drugs, exchange bankruptcies, long waiting time for first 3 confirmations, missing support and mainly, they don't won't to be responsible for their own money. yes, it is so simple..
There should be this thinking that many are doing transactions that is why it takes so long and the ledger is getting bigger.
That's true, a lot of people forgets about that, the many queues of the transaction can make a long time for the system to giving any confirmation for every transaction.
And then it's normal for me if the confirmation will taking a more time.
