Re: ICO buying experience.
I think the first ICO I bought was ICN or Iconomi. Its very successful ICO and having a good price when it was put on exchanges. If you are joining ICO, see to it that it is run by legit organization or people with good track record. Be careful always as there are also scammers.
Sadly, most project at now are scammer or do not clearly, so very difficult when we want confirm an ICOs project really or fake. Fortunately, in Bitcointalk Forum still have many people helps us solve this problem, example @cryptodevil had blocked Karbon, Lust ICO project in past time.
