Salt seems very promising as well. I like that anyone can loan out their coinage and get something in return. I'd never take USD for loaning out Bitcoin but this is compelling. I almost got into Bitconnect until i saw their structure and it screamed pyramid scheme. Salt is also quite inexpensive compared to OMG so it is easier to get in.
I don't think Salt and OMG will be competitors at all and having both looks like a good idea at this time.
I am trying bit connect you dont need to have others signed up under you for it to work. So far in one week i have mafe $9 in interests. i only put $100 in it to test it. I am also liking Spectre.
Interesting, I have an account on BitConnect as well but never used it. It's a shame you cant get that $9 out for a while though.
