Everyone needs to remember that the exchanges play only a very small role in the cryptocurrency valuation. The most important factors are the viability of the project, reputation of the team members, adherence to the timeline and legal status of the project. Exchanges come in to picture in a later phase, after the ICO is completed. If the project is a good one, then it will survive even if no major exchanges list the token. On the other hand, if the project is not adhering the timeline, then there will be no use even of it is listed in a major exchange such as Binance or OKEx (normally these exchanges won't allow shit projects to be listed).
Big exchanges are always very serious about listing a new coin because they often evaluate the project very carefully and must meet the criteria to be listed here. I usually choose good projects at Binance exchange because this is an exchange that allows investors to liquidate at any time and the trading volume is always very high, so evaluating a good project is very easy.
Also before investing you should monitor some fluctuations of this market because if you do not invest in the right time, you will face a lot of big risks.
