Article came out recently about how Korean exchanges might be completely banned soon. Might want to move a little BTC into USDT if you are uncomfortable with volatility. We MIGHT see some kind of significant drops over the next few days depending on how this pans out. Just remember, we made it through the China ban and still are doing great. This will just a be a bump in the road if anything happens.
Do not panic, when you panic you lose the most. Remember in the past what you have done during volatile/bad times. If they were successful, repeat them. If they were unsuccessful, think about why (most likely cause of panic selling) and correct your previous mistakes
