Nowadays it is really hard to trust ICOs, from what I've experienced with ICO is really tough that is the reason why I stop here and now I'm back because i've heard about IEO and I think that is a good start again to look fortune here. But if there's still a scam in IEO maybe i'll be focusing in my current work.
Most of the time, investors focused solely on BTC. Perhaps altcoins can hardly grow fast again, so they only choose their main investment is BTC. ICOs do not seem to be a good option and instead IEO will be more secure.
