I skipped usi and went to genesis mining https://steemit.com/cryptocurrency/@maryoush/another-part-of-my-portfolio-is-cloud-mining-15-share and bitconnect as a small diversification https://steemit.com/cryptocurrency/@maryoush/10-of-my-portfolio-invested-into-system
However, i would say that usi is definitely very interesing and even easier to use. Good luck dude.
Cheers mate good luck with genesis(they have been here for quite sometimes and will be there for a very long time too) and bitconnect. Glad to connect.
