If we get loss then we need patience. go forward with long term investment policy. we must get good benefits by long term investment policy.
Long term investment is another strategy in trading. Time is a great ally here. Dealing losses with trading is one of my fear before. Now, I learned to spread my investment and divided to long term and short term. Now, If I lose on another, I see to it that I gain on another coin. That is trading, you have some losses and gains. Be wise enough to formulate your strategy.
Long term investment is always a better way to earn good relative to the profit earned from trading. It's good to make a research about the coins that are existing periodically and make a buy and hold it long. If lucky might experience a sudden pumping as the one happened recently with several coins starting from eth, doge and so on.
