You're right, actually it's a simple thing. If we decide to join and support a project, we must be prepared with all the risks. So do the best analysis possible, accept the risks that might occur, and do it according to ability and willingness.
for people who are able and willing to take certain risks they will be calm in choosing a project. but without those who do not have good analytical skills, all of them must also be prepared to face the risks they have chosen.
