Whatever suits best for you. Any of these are not better than the other.
Well
You should try with Penny Stocks Trading (you can find more info here: http://pennystocks.toptips.org)
Penny stocks, also known as cent stocks in some countries, are common shares of small public companies that trade at low prices per share.
I've been subscribing to this PennyStock web site for about a year now and have loved the objective advice they give. He really does look for quality stocks and I've made some pretty nice profits on a lot of his suggestions. Being still fairly new to investing I have been dabbling a lot in penny stocks to try and grow my account. I may not have a big account, but it's a lot bigger than it was a year ago. On just one of Nathan's picks this year I managed to make my investment back ten-fold! Be careful! Penny stocks are notoriously risky but if you follow the right method the risk is almost 0. I suggest to invest only little money first and then reinvest the profits. This is the site I'm using: http://pennystocks.toptips.org
Hope it helps.
I'm making big money with binary option, I use this software ( http://forexsignal.kyma.info ) My software delivers signals only when the five indicators (bp trend filter, market deviation, price pattern, rel. price impulse, stat. price range) are aligned together and we have an extremely high confidence rate, it must then co-exist with my proven secret strategy before a trade be detected… as a result, we get a guaranteed Highly-Accurate ’80-100%’ Signal.
There is no better security than Linux. Do not use Ubuntu. Use a serious Linux like Centos.

Windows, Linux or OSX?
