I don't think long investment is bad. If you reasonably trust the project, you may afford yourself to wait for a while to get more money. So, for me, everything depends on the certain platform. I scrutinize its technical documents to be sure that it's safe, then only I can make a long-term investment. Cyber security really matters. I want my transaction to be safe, and this is only possible when the platform is protected against attacks, like in CYBR solution.
