Yes, we hold altcoins because of altcoins and IEO are future of investment. Like moozicore is really interesting project I invest in moozicore and I suggest you to invest in Moozicore.
Although, I agree that altcoins, but not all will still make headway, come what may, but I do not agree that IEO is the future. The rate at which IEO started compared to now, seems to be dwindling. Except there are other ways around it, to name the fundraising through IEO to be more effective.
