As you know IEO trend is growing but i feel IEO is profitable only for those who invested in token sale but who have purchased altcoin after launched they suffer loss majority of the investors ,as the BTT and some other altcoin examples of IEO.
IEOs that have good promotion and good team behind are the profitable ones. There are IEOs that are failing due to bad.promotion and there not unique strategy. We should choose an IEOs that can increase our capital.
That's easy to say to choose the right IEO but actually in reality it's to find a good one since the market is very unpredictable and in general altcoins are still not that promising compared to the past. When investing in IEO we should not look for a short term result as we might get disappointed when altcoins dump which would result to a bad market of IEO as well.
