Still waiting for bitcoin to rise, it has been dropping since I bought...
Standard investing wisdom says, when the price is rising, sell. Went the price is dropping, buy.
The method for buying and selling should be based on a general program of buy or selling in chunks. Markets generally do not make long-term moves overnight. There are exceptions, like Microsoft in its early days. And, there are many penny stocks that disappear forever. But generally, do something like increasing or decreasing your holdings by a percentage or amount you are comfortable with, on a regular basis.
If the market is dropping, buy, a little this week, a little next week, a little the following week, and so on. If the market is rising, sell, a little this week, a little next week, a little the following week, and so on. Make your own rules and follow them.
Use a percentage of your balance for selling. That way you always remain in the market. Use an amount for buying. That way the purchase doesn't go beyond your means.
