Hi. Be calm is the best thing to do when the market is falling. Study the market of your token you hold if the value is fluctuating and the activities of the project why it causes to fall. Sometimes it falls because of the value of bitcoin or the market of the project is not worth it. If you think the project is active in the market but the value is still low, then keep it hold or buy more. But if the project you think has no progress even they have some activities doing, then maybe you think twice if you buy more or just hold only and find another project that is better.
