but, mining ETH risks also not too big, just buy mining tools, building mining RIG and buy a few VGA, I think it is good enough for it.
or take a little risk and investment in ICO's, it could be huge profits, can even get a 2-3 fold.
The mining Ethereum is get less profitable now, especially for the people with high electricity price and old GPU.
ETH seems to be a coin that will go down in the future, I would not mine it nor invest in it. The coin I think that will prosper on the short term is stellar and bitshares. Other coins seems to be rip of off others which means no innovation and no future.
