some people don't like decentralization, because it take away the security, you need always to trust a third party with decentralized system, that's the only problem i can see, otherwise decentralization is the future
Can you clarify this point? One of the key innovations of Bitcoin's decentralized consensus model is that it does away with the need to trust third parties in a transaction.
I think he is referring to paying using Bitcoin vs. paying using Visa or MasterCard, where the credit card company will usually refund the transaction in the event that there is fraud on the part of the seller. So to get back that assurance, you would need to use a trusted intermediary like an escrow.
