it all depends on the potential of the coins that I hold because not all coins have a good future, but I prefer holding long-term coins that have the potential to grow in price in the future.

the best time to sell it, in my opinion, is when the price of the coin has reached higher than when the price we get it, so we will be able to get a profit, but need to remember in doing our trade do not be too ambitious to get big profits, better profit but can continue rather than once get a big profit and then lose money in the future.
