If you are a crypto newbie start from point 1. If you already invested money into cryptos then start from point 2.
1. Invest only the amount you can afford to lose without even sweating about it.
2. Wait for the rise of the value of your investment around 2x and then pull out the amount of your initial investment. This way it's like you never invested and you still have a profit, and a portfolio.
3. When you receive some extra profit put that aside too - open yourself a little "crisis fund".
4. When the crisis happens, look for the prices of travel to the tropical country you always wanted to visit.
5. Activate your "crisis fund".
6. Take your family on a vacation and enjoy the sunshine while everybody else is panicking.
7. Return from the vacation and irregularly check your portfolio to enjoy the rise in value.
8. Repeat steps 3-8.
Your strategy looks good but I think this will work only on the perfect world. No offense but this plan will only work if you are really settled financially. There are people who's struggling to their daily financial needs that even on 10% gain will withdraw there profit from their investment or trade or worst withdraw the money at loss. But still you have good plan most especially the vacation one that's very good suggestion I really like it.
