of course ICO, because i have a lot of sweet memory in ICO and i want the hype on ICO return again to this crypto world my friend
Everyone who has felt sweetness ICO in 2017 will want to come back again 
, because we can get a lot of money from ICO projects, Unlike the current IEO or Defi project, it doesn't give us as much money as ICO project in 2017. Currently, Many IEO and Defi projects are scam, especially Defi project, they only use pump and dump moment, after that their projects die.
