The area of support can be changing to resistance if the price keep down, to minimize the risk is better use stop loss so we can buy again in another lower of support area and we get more amount of coins. Use stop loss by 6% is good, so if the price keep down more than 6% we can buy again at the bottom price.
For now I think we are quite safe still,,, for the moment the key support has still remained strong, which is 30k,,, we were all disappointed about 35k but I think this is a temporary dip and the bounce should start once Asia goes to be, which is where the strong sellers are right now thanks to China news.
