The Triffin Dilemma, where countries issuing reserve currencies attempt to simultaneously manage national savings levels with necessary international liquidity, continues to act as a barrier to economic growth. However, could it be that the introduction of bitcoin brings forth a viable solution to the Triffin Dilemma?
If we assume that the prerequisites for a currency capable of solving the Triffin dilemma were to provide the following, it may be possible to argue that bitcoin is the perfect fit.
1. Stable value
2. Rule-based issuance
3. Manageable supply schedule
Never cannot be bitcoin the solution of this kind of problem.
First because is far away of being stable in value. And who knows if it will be some day in that measure asked by being reserve currency. This is because bitcoin have no owner to take care about it and to contribute on its stability managing it as is made with every normal centralized currency actually by the Central Bank which issued each of those.
Indirectly the last sentence bring in light even the second point of my written: the incapacity for no one to manage bitcoin. Being decentralized as a currency, bitcoin is totally free and act only according to its "mind". Its supply might be fixed and as such, known, but this doesn't mean that can be managed as it is needed for the economy. In different times may have need for more reserves or more need in the market than the value of this kind of reserve. With every kind of centralized other money is easy to realize that because its supply is not fixed and can be re sized. So can fulfill all the needs in every moment will be need according exactly to this need. With bitcoin is impossible. Cannot be produced in time and during the time over the quantity predefined from Satoshi.
