As the market is showing some volatility ask yourself this question. Did you DYOR research before you bought your crypto? I hope the answer is yes. Now if you are planning to hold on to your crypto for the long term then does it really matter if the price goes down now in the short term? Your research would have likely said this is possible but it also likely said that it will rise substantially over the period you plan to hold it. So remain calm. Also in a dream scenario you have bought coins in a few units say 2-5. If so the best thing to do is this; sell one or a part of a unit once the reaches the level of your initial investment. Then what you are left with is free crypto, pure profits. You could then sell some more units 1-2 in the medium term to enjoy some of your profits and leave the rest for a very long time and watch it just grow and grow. That in my opinion is what smart investment looks like.
