Uhmm.. let me share mine.
First time following pre-sale (although not private sale) is in Alpha Finance through Binance launchpad. Before i decide to participate in binance launchpad for that project, yes, i did some DYOR mf mine, Which are :
1. Team behind the project. (Must gave clear information)
2. Whitepaper (are whitepaper written well, no plagiarism nor anything)
3. Roadmap.
4. Funds allocation (during softcap, hardcap)
5. Project Uniqueness (What makes this project different from other projects)
6. Risk Management (Always invest with money you can afford to lose)
Those 6 steps usually applied even when i decide to invest in other project (old or new project).
And about "medicalveda". I tend to agree with this comment :
read all comments by clciking quote link.. very nice comments
Afaik, 90% projects that mentioned about health or housing as their main purpose or 3D printing.. usually ended as useless project. Dont forget, Health is expensive business.
