Bitcoin went up again and stood back above $12,500.

Bitcoin has regained its position above $12,600 today from the July 7 low of $11,050, and the 24-hour increase is close to 10%, driving other currencies to rise.

Despite the recent fall from the 2019 high, Bitcoin has risen more than doubled since the beginning of 2019, especially after Facebook announced the launch of the digital Chinese currency Libra.

The recent skyrocketing has made many investment experts analogous to the trend in 2017, but many believe that there is still some key difference between this year’s price rebound and the chasing of the past.

Blockchain analysis firm Chainalysis released a report last week saying that bitcoin trading volume in the illegal online market, commonly known as “dark net” in 2019, is expected to exceed $1 billion, a record high, surpassing the previous record of $872 million in 2017. According to the report, the amount of bitcoin transactions on the “dark net” has reached about $515 million so far this year.
