When the bitcoin goes sky rocket high, then its time to cash out those coins. Either spend it for insurance of your loved ones or use it so start of your passion business. You could also keep it for emergency money. What's important here is to not spend it in gambling or waste it.
Simple, use it wisely. Only important thing or the most needed thing you should buy to,because money easily disappears. In my part, I will buy it house and lot and create a small business which can help my daily needs, and also I will continue to invest bitcoin again and again.
