I believe that DIW is one of the best ICOs to invest in March. It's currently at PRE-ICO and doing well. Do your own due diligence if you are interested in investing, and see for yourself that this is worth looking into and possibly investing too. There are so many things happening in the DIW world right now, Announcements are coming in on a weekly basis, some of which are new expert advisors joining the team, new meetings at abroad summits with experts from around the globe and soon to be announced will be the exchanges to be listed.
Definitely worth looking into and you will not be disappointed.
