1. The team is experienced in technology so their concept will be good if it is experienced.
I'd agree with this but if the team is experienced in technology, they must also know what are the things that will benefit most of the people the most. A good concept = good project. If it benefits the people then it can be considered a good one.
2. Funds must be prepared because building a project must have funds. Do not rely on funds from the sale of ICO / IEO. It will be difficult if the project does not develop.
I doubt that most of the projects started with some funds because anybody can just create a team, make a project and market/advertise it on social media platforms. Although I'm not saying that all started with no funds because I believe that there are some that have some funds enough to pay the partners of the team and some advertisements too.
4. Good marketing and can build a community with many who are interested in the project.
Marketing is a must in creating a project. A project can be successful if the marketing team is good and vice versa.
5. Do not underestimate tokens at the entry into the low exchange because it will anger the investors.
All the projects starts at the lowest part so just understand this thing. There are some projects who just started their project but they listed it on a popular exchanges like Binance, Kraken etc. and they expect that they will be doing the same.
