You're being offered 2 free tokens, presently worth nearly a dollar. You don't have to do anything, but signup to get it. There is no other obligation. Of course, with any ICO you must be cautious about buying into it, because some have been rip-offs. Some people's strategies have been to get in, and when reaching a certain amount such as $20, $40, or maybe a little more, would cash out and move on.
Only in this case, you're not buying anything, but getting two free coins in the ICO, because they're encouraging more buyers to support before going full public sales.
My personal strategy with this one, is to sit on it for awhile, to see their reputation and watch it grow. Once it reaches a certain amount allowable for lending, then I'm going to move it into their lending option, and see it gain daily interest, then I will re-lend the gains. If this one is as stable as they claim it to be, then they should be paying out upon request. If they do prove stable, as such, then I will stick with it for a while.
If you think you'd like to try it out, then you can go to my YouTube channel Parcke075, to the Entrepreneur tab, the only video there, then go to the third link at the bottom.
