It could happen to anyone. It depends on luck. The best thing is never regret what you've done. Just think if you didn't sell your xvg, the price might be lower the following day. Who knows?
Off course i prefer to hold over than to have a big regrets, i am confident that all people should not panic and just hold there coins and wait until the market will be green and i know it can happen next month so keep holding and dont ever sell now.
