Now that there are about 3 months left before Bitcoin halved, there is no doubt that miners are most affected by the halving. If the price of Bitcoin is still at the current price level after halving, this will cause huge losses to the mining . If Bitcoin continues to stagnate, then this panic may worsen with the halving, and mining may be facing its biggest turning point in years.

Seven, central bank digital currency and Libra
Sweden took the lead and started testing the central bank's digital currency, and it is even expected to become the first country to eat crabs. In 2020, the central bank's digital currency has received great attention, and important progress is expected, and it is even expected to see the birth of the first central bank digital currency. Libra is also developing steadily. The initial development path seems to be too aggressive, which has led to regulatory resistance. Now Libra seems to intend to start with the US dollar and anchor a single currency, which may make Libra's road more stable.
