I had a look at their website and in their terms and conditions they write this:

"Proceed with caution. Channels is new and we offer no guarantees whatsoever. Any investment in time or money you make in Channels could be lost at any time. We may choose to discontinue Channels at any time. Any balance and content we are holding for you could be lost."

So anytime they could just close their website and any money you have in there can be gone overnight...

Nah, that sounds not exactly trustworthy I think.

Better to stay with Steemit.

My 2 cents to it.
