Yes, it seems IEO is getting lower but it doesn't mean IEO is ending like the ICO projects, rather big exchange stopped bringing a new IEO as the market condition is not stable at all. Therefore people are more focusing on buying Bitcoin and Ethereum as the best buying time has come after a long period, so, they won't invest in a new coin.
Now very few IEO projects are good for investors because the current market is unstable and the risk is often very high. I think it is best to only join IEO at large exchanges like Huobi or Binance because this is often the place where there are many successful IEO projects and always bring a lot of profits to investors. However, you need to consider many times because IEO investment is not usually recommended in the bear market.
