1. When we are in a bull market, most of the altcoins are surging in price. It will only depends on you. What is your purpose? Are you holding that coin for long term? Or for short to mid term? If you plan to hold that coin for short to mid term only (just for this bull run), I believe most of the projects that have been launched on Binance will increase in price during the bull run. Now if you want to hold it for long term, maybe do some research on it, but there's no assurance that the project will become a successful. One thing's for sure though, the project's token will have a price where you can just sell it.

2. How you can detect? You can't unless you have an insider. You can't predict the future of the project. One project can be called the best as of this moment, another one can be the other day. Projects that might be the best currently will not be the best a few years from now. Rating system on different websites will not help you either because there is a chance that the project paid them to give them a high rating.

3. None. I would rather invest into altcoins that are at the lower market cap (around 51-100 in terms of market cap) than investing into these new projects. Even though they are being listed on the most popular exchange, there's a chance that the project could end up as a failed project or at least the project will not become as popular as other Binance launchpad projects out there.
