Thank you for asking. Nagalim said exactly. Just a few points to add.
The Tube will just work in the same way and will still be important by acting the role of spot product (+1x Bitcoin) trading and settlement. On the other hand, the establish of ETP A will enlarge the NLG Pools, and thus stengthen the liquidity support on the NBT/BTC pair on the Tube, and let us have more room to support more trading pairs on the Tube in future, such as NBT/ETH.
Regarding the newly created NuBits demand, we had a very rough estimation here:
Generally speaking, in an economy, the size of financial assets people holding and trading is much more than the size of cash in circulation. The volume of derivatives trades is much more than the volume of basic securities trades. Although the exact number of NBT demand can not be determined at the moment, we believe that ETP is the right direction, which NuShareholders should support, and will be rewarding. Moreover, ETP creates a secondary asset market of NuBits, and establishes a new business framework, Its potential should not underestimated, for example, it can evolve in the future by expanding the products to link to other assets such as NSR, or even crude oil and SP500, and by upgrading the technical features with latest techs such as PeerAsset.
P.S.
As poeple can tell from the name, ETP is designed on the idea of ETF(exchange-traded fund). we made some fine tuning to fit NuBits better. the following are good references for ETF.
