why not trying to buy or ivest in IEO from big exchange like Binance, Huobi, Kucoin and etc.
as i remember when project are launching IEO on this exchange are ended successfully and pumped until x2-x10 after listing and tradable
not all projects will be as successful as you think, even though those listed on the IEO are large exchanges. I followed some IEO, it looks safer and faster, but it makes the investment cycle in new projects also go very fast. many investors take off their coins when trading opens. not much to hold back for long.
Investors, will not bother how much money he made through his holding in long terms, most of the IEO investors will move when they made a profit after listing in the exchanges. In some exchanges like Binance after their IEO, the price of coin increased a lot, which people who invested already made good profits.
