Voted for trading, and the result also saying that Trade is the winner of this Poll.HYIP, RevShare, Cloud, are mostly scam(Ponzi), Gambling is luck near to me.I have lost some of my BTC joining bet and earned very little.Trading is only the best source of bitcoin now.Although I have a little skill on trading but I saw, many people earning a lot of money by trading.In this forum most people earned by trading.
I believe that not everyone ends up making money from trading. You might be at the lucky side and you got your profit but there are people on the other side that lost their money because they got scared and the panic sold their coins, or they simply just got tired of waiting and chose to get sell their coins at a price lower than they got it.
Almost everything is based on luck. Not to promote HYIP sites but just to use it as an example or any ponzi site, actually. You can get lucky enough and invest in an investment site at its early age and then be lucky enough that the site would run more than the time needed for you to get your ROI and so you'll get your profit. Even the most legit type of investment like investing in a real world company can turn into a bad investment if you get unlucky.
