Bitcoin is very volatile; you can buy Bitcoin today, and the price can drop in the next few minutes. This doesn't mean you have lost the value of your Bitcoin or that the price will continue to fall and won't rise again. You have to understand volatility before investing in Bitcoin.
If you are investing, you are suppose to know about what you are investing in, it’s not just going to make sense that you making investment, and you don’t have proper knowledge about what you investing in, and as long as you are doing research about bitcoin investment, then you will definitely come across bitcoin volatility.
After investing and you discover that the coin price drops, all you need to do is just to hold, what’s dropping is just the value of the coin, but the amount of the coin which you are holding is still the same, so even if bitcoin price crashes, all you need to do is just to hold, with time the price will bounce back. Most people do panic when bitcoin price drops, but I don’t see anything to panic about, that’s why when investing, our target should always be a long term target. If you are holding for long term, all the market slight changes in the market won’t really disturb you.
