Korean and China governments were too late to put regulation before the crypto-world took off in 2017.
Don't panic on news regarding these countries to ban or trade. China nor Korea cannot ban cryptocurrency.

What Korea government wants:
1) Government first wants everyone to sell their cryptocurrencies.
2) Then they will issue licence to exchanges to legally operate in country.
3) Let people start to buy/sell again, but this time without anonymity, by registering individual's names, accounts. So government can track who earned how much money from trading.
4) Government will get tax from the gains.

Only in Korea, the number of people who trade cryptocurrency is enough to take down government by protests, in case of a permanent ban. That's why Korea president was so afraid and immediately had to declare that they don't ban cryptocurrency.
So, there will be no ban, but incoming regulations on trading & taxing.

Remember how Uber disrupted taxi industry in all countries?...And taxi drivers protested, pushed governments to take action against Uber...Years of war has been going between Uber and governments. But guess what, it had been already take off. Governments cannot prevent Uber or Uber-like apps that will serve the same function. Similar case for Airbnb...
Same for digital currency. No matter how big pressure comes from governments, as long as 2 person still makes transaction, digital currency will survive.
But we are not at that point. More and more companies, banks accept the digital currency era is coming and started to work about it. Only stupid ones are neglecting and pushing government to prevent it. Smart companies are accepting and trying to adapt for future.

I don't have any advice on which coin will rise or fall. But remember: it's here to stay; so don't panic. Fall and Rise is nature of trading.
