What is GRT virtual currency
Strictly speaking, there is no issue price for bitcoin. In 2010, a programmer bought a pizza with 10000 bitcoins, the first bitcoin deal
bitcoin does not rely on a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

GRT means gross tonnage
gross tonnage minus cubic feet of space reserved for crew living quarters, cabin, fuel tank, engine room, bridge, material room and ballast, that is, the actual carrying capacity of the hull under the upper deck (or so-called enclosed space of cabin), calculated as per 100 cubic feet (about 2.83 cubic meters)
gross tonnage is the basis for calculating port charges, mooring charges and terminal berthing charges
For example: ships of 3 000 gross registered tons (GRT) or more and all gas carriers are required to engage apilot

also known as registered gross tonnage, it refers to the sum of the internal space (or volume) of all closed places in the cabin and on the deck. It is the quotient of one ton of 100 cubic feet or 2.83 cubic meters
gross tonnage is widely used, it can be used for national statistics of merchant fleet; Indicate the size of the vessel; For ship registration; It is used for the government to determine the subsidy or shipbuilding allowance for the shipping instry; it is used to calculate the insurance cost, shipbuilding cost and ship compensation, etc.
registered
tonnage, that is, the total registered (volume) tons
NRT: net registered tonnage
DWT: dead weight tonnage
dwcc: dead weight cargo capacity
I think GRT / NRT is more important in ship logistics, dwcc may be the key to delimit the ship's load limit.
