For now I'm more recommending buying when on a private sale or during the IEO
Binance, Huobi, Gate.io, these exchanges are very good to follow, the average project that holds an IEO there always ends successfully trading above the IEO price
If you are able to be lucky and have the opportunities to invest during the launchpad then it's very much anticipated that the chance of getting decent profits is there for you when you work with binance, IEOs that being held inside this exchange have a higher chance to grow in value after the launchpad has ended, it's a chance that shouldn't be missed by any investors to take place.
