Ill answer your question. So the forks of Bitcoin have been announced or gained public awareness last week or around 10 days ago. The Koreans are having a7 day eating holding so they are not doing any day trading. On Saturday there was a rise in the price and some are buying before Monday. On Sunday some Korean markets have started to increase trading. Oh BTW on Monday the market will probably explode and the price of Bitcoin will probably surpass $5000 by the end of the week.

Of course, altcoins might suffer as big Youtubers are converting their currencies to Bitcoin.
