What can I do to minimize my risk?
To diversify. If you diversify your investment portfolio in different projects you minimize the risk. You can choose, for example, between contributing 100.000 € in a single project or making contributions of 10.000 € in 10 different projects. In the first case, if something happens to the project, you put the total investment at risk. In the second, all projects would have to fail to put the total investment at risk.
