The plan is to go decentralized in the near future.
The added layer of security (e.g. the central node approving/rejecting blocks) will be soon removed to create a fully decentralized e-commerce platform.
Also, we do NOT disapprove the creation of other exchanges around RLC. We want a competitive market because it is in the best interest of all.
Lastly, as stated before, we plan to become a PayPal alternative and not a competing cryptocurrency. The reason behind this, is that there is a need for a really low cost global payment gateway without foolish restrictions, frozen accounts, difficult procedures and the Bitcoin platform serves as the perfect foundation for such a service.
On a side note, we will gear towards being 100% legal (following all AML/KYC procedures) as far as the exchange goes. Now the RLC network is a different story and soon it will be fully decentralized thus having all the benefits that a p2p platform offers.
