The minimum investment you can do on genesis is $30 if you want Ethereum mining power (1mh/s) or $50 for Monero (50h/s). Both contracts are for 2 years, and those are the only 2 available at the moment. If you pay with credit card you need to wait 30 days before getting your first payout, otherwise you get those immediately. You get your payouts every 2 days (if you reach the minimum values) with the smallest possible option you will probably wait 6 months before getting a payment (ETH are 0.05 minimum payout which is around $16)... On stats normally you get around 17%-22% of your return every 2 months.
If you are planning to use it, feel free to use my promo code 'JW53Qp' when you purchase. You will get 3.5% off.
If you have other questions feel free to ask... overall almost everybody has a bit of power on genesis, you will not be rich, but you actually make a nice premium literally without doing anything.
thanks i will look into it
