I don't agree with you, Bitcoin is a big alternative on the tarrif war, despite some of these countries alliance with each others to ease the impact of tariff war, China in particular has been doing underground business transactions with Russia.
And how will Bitcoin save China's exports to the USA in this tariff war?
Bitcoin is just a currency, it doesn't matter how you use it and who uses it, The moment a country says everything entering the customs from one other country will be tarriffed 120% it doens't matter how you apdi for, euros, USD, bitcoin, gold, it will still be taxed 120%.
Let's assume Amazon will pay for all its China imports with Bitcoin, how will this avoid tariffs when the value of the goods will be taxed in the customs?
Seriously, how in the name of god will crypto solve anything in this tariff war?
Economically speaking, the impact of the tarrif war will affect Amazon because is a US based company. Before now, trades were not settled with Bitcoin between US, China and others countries, but considering other countries with similar tarrif issues with the US; it becomes possible to settle international trades with Bitcoin if other countries has this trades agreement, and the impact of the tariff war will be reduced.
Again, international settlement currency is the US dollar not Bitcoin, and that is one of the reasons the US has been increasing the tarrif rates.
Try to understand the simple economics structure, If Amazon is a Russian based company for instance, settlement is possible with Bitcoin. In addition, US dollar is the world international trade exchange currency, until now, there has not been an alternative means of settling international trade transactions basically because of exchange rate barriers plus other factors, but with Bitcoin, trades globally can be agreed and settled with Bitcoin payments even if these good are valued in US dollar at the point of purchase.
I would love a situation where we can go deeper in to the economics of those whole tariff war besides some political aspects. First, talking about GDP in relations with imports of a country.
In summary, and as an economics,bi think the US has the capacity to produce most of these imported goods from China, but they had decided to import these items due to many factors that we may not discuss at once here.
Now, every nation wants to be wealthy, and economically strong. To achieve this fit, GDP must be very strong, otherwise a notion's economy will suffer, it can even lead to hyper inflation if not handle properly etc.
