Last year, the price of Bitcoin rose by more than 200% in the long run, above the price of the foreign currency platforms last year. The price of Bitcoin in the domestic platforms was higher than the price of foreign currency platforms by more than 200% for the majority of the time. I wrote an article about OKCoin as a domestic platform, OKCoin as a foreign platform, and I also found out if there is a chance of a long-term gain here. The only way to understand this is that the price of the domestic platform once maintained a 15% premium over the foreign platforms. But I was wondering how to eat this part of the premium through the leverage.
