No matter how promising a project might look, especially if they are new projects just look them as if they have nothing to offer and invest only what you can afford to lose. Do not keep your eggs in one basket, do not fall in love with a single coin, no matter how good they are always keep digging, many more good gems won't hurt than relying on a single gem 💍. Be smart
Quick but direct to the point. Many so called promising projects has dealt with us in many ways which makes me to understand that it is good to look beyond what the team displays or what so called partnership, news etc they have and focus on the possibility of that project making it. And even at this, we humans are unpredictable, investing what one can afford and being contented with it is possibily the best. Also, even though there are many untrustworthy projects, there are also trusted ones and therefore taking a glance on those ones (listed with evidence of growth) is worth the time.
