as a project investor you must be wiser before investing in a project and will never open your wallet for any project without thinking about it 10 times or even 20 times. At that time or precisely in 2017, almost all ICOs were seen as potentially profitable companies and people assumed that there would never be an end to the boom that occurred in the entire cryptocurrency market. And then reality struck.
Today, the landscape has changed a lot and those who are burning leave the market completely or they continue but with a different mindset emerging from an unforgettable and sometimes regrettable experience. Investors demand more information and they want to be given real facts only because of the inclusion of the IEO project in a leading exchange. In 2019, it might be rather difficult to distinguish trends in knowing which types of projects might be a big success because there are many factors that need to be considered, but we hope that above all investors are more mature, more demanding and more discriminatory. Once again consider before investing in a project and don't give bait to the scamers out there!
Personal research and/or, due diligence should never be ignored no matter the project, no matter the hype, no matter the so called experts supporting it. If we can clearly understand the Importance of studying every project before investing, then I think we will go a long way in stopping bad projects from seeing the light of exchanges. But nowadays, the reverse is the case, once hype is sensed around a project or once a crypto expert, influencer, or analysts says a project is good, most people rushes to invest without doing the right thing. Therefore, just like you pointed out, a wise investor considers many factors and make the best decision towards investing in any project.
