SALT looks somewhat legit, although I don't think the developement is completed. I think SALT has actually submitted itself to regulation, which is pretty important in the lending world.
Bitconnect looks like an unregulated Ponzi, Pyramid, and HYIP scheme all rolled into one.
Salt and bitconnect has different system
As i know salt is pèer to peer lending platform
But bitconnect is pure ponzi scheme
Without special feature inside,
, correct me if i'am wrong
