- Buying and holding, the so called HODlers. Buy promising coins and hold them for a longer time. This strategy is actually a very good value keeper strategy since at least the established coins seem to gain value over time.
- Use the API for investing either based on algorithms related to trends or value fluctuations or perhaps even on AI. This is probably a very profitable strategy but requires knowledge and sw development skills (unless you can afford to hire a team).
- Study and investigate and follow the news about different coins, this requires time and effort for the study. May be very good and profitable approach if you have the time.
- Whales I will not mention, they have their resources and money.
- Very long time investing in coins that seem to gain profit, this requires a lot of time and patience but may end up well.
