Bitcoin is a currency with a future. Don't be fooled by fluctuations, it will save a lot in the long run. There have been a lot of fluctuations due to the pandemic but the next year will be better. Its bitcoin mining is being done, serious investments have been made. The raid on the Okex stock market also caused bitcoin prices to drop slightly. Everyone in our trading group expects good increases. This situation will improve soon. Personally, I also turned to bitcoin mining this year. The increase will be upwards.
