Nubits is a cryptocurrency pegged to the USD. It's done so successfully for 1.5 years. As part of its liquidity control operations, when BTC price rises, Nu uses "parking" to rein in extra Nubits on the market.

Now Nushareholders are offering ~12%APR for 3 month to 23 days and 8%APR for 11-23days.

Just buy Nubits, park them (do it in your wallet), and the "interest" will be paid by the blockchain at the end of the period. The park rates are often changed according to market conditions. Once you park, your rate is fixed.


You can buy Nubits here (most liquid exchanges are poloniex and the NuLagoon Tube).

Edit to add:
You can find a parking calculator, a tutorial, and an FAQ at www.parkyournubits.com or http://parkyournubits.com (both also with SSL support if you want).
