Looks like the effectiveness of ICO system which is the first and popular method to collect funds for many crypto projects has now passed and no more future anymore and transformed into IEO to avoid possible runaway of investors and exit scam and until now its the most recommended to every projects looking for additional funds.
The crypto market is very dynamic, ICO was once popular and provided many benefits. It's just that, many fraudsters use ICO to make fake projects and embezzle investor money. IEO is now more popular, supported by trusted exchanges, attracting more investors to join. Someday the IEO era will end and be replaced by more effective sales strategies.
Refusing to forget, here are some of the last ICOs. Some of them then held IEO at Binance. Do you know which one?
