True. Time plays a big role in trading or investment. If we choose a bad time to buy, we will get difficulties selling it. The price can drop for few months and be hard to increase again. So, we must be careful to determine the best time to buy a crypto coin. Just buy the coin if it looks like to have a big chance to increase in the next few days/weeks. So, even if we plan for a short time, we are not difficult to sell it.
