SEOUL, Feb. 1 (Xinhua) -- South Korean President Moon Jae-in's approval rating rebounded this week on the eased controversy over the government's regulation on cryptocurrencies and the first unified Olympic team between the two Koreas, a poll showed Thursday.

According to the Realmeter survey, support for Moon was 62.6 percent this week, up 1.8 percentage points from a week earlier.

It was based on the survey of 1,501 voters conducted from Monday to Wednesday. It had 2.5 percentage points in margin of error with a 95 percent confidence level.

Controversy arose over the government's regulation on cryptocurrencies, including Bitcoin, as speculative investment surged especially among young voters.

It was moderated as time went by amid spreading views that the speculative investment should be regulated.

South Korea and the Democratic People's Republic of Korea (DPRK) agreed to field a joint women's ice hockey team during the upcoming Winter Olympics, which were scheduled to kick off on Feb. 9 at South Korea's eastern county of PyeongChang.

Some of South Koreans criticized the first unified Olympic team between the two Koreas as South Korean athletes could be at a disadvantage for the hurried decision on the joint team just ahead of the start of the Winter Olympics.

The criticism reduced amid growing views that the unified team would help ease tensions and boost peace on the Korean Peninsula.

Moon's ruling Democratic Party kept the top post with 48.5 percent in support scores, trailed by the main opposition Liberty Korea Party with 19.7 percent.

The minor conservative Righteous Party gained 5.8 percent of support, while the minor progressive Justice Party won 5.5 percent. The centrist People's Party recorded 4.7 percent in approval rating.
