I was not joking. Check this:  http://coinspool.cu.cc/info_roicoin

It does show hodl algorithm. Low difficulty and it's easy to mine with regular computer and solo mining. It's just on exchange though ( https://coinsmarkets.com/trade-BTC-ROI.htm ) but its' worth more than HODL.

HODL right now is 0.00000016 BTC and ROI is around 0.0000004 BTC. I have a feeling that someone took HODL coin system and idea and created ROI coin.
