I hear mining is dead now, and you need to invest alot more than before. I was considering mining, but I see it as a waste of money.
That depends on what you're mining and what hardware you're using to do it. ASICs using Avalon chips seem to be available soon and are rather cheap compared to alternatives. GPU mining is still profitable for scrypt-based altcoins.
My main method is gambling (I use a special technique to always win), I havent lost a game in a long time (will post tutorial if anyone is interested).
Unless you actually post the tutorial, I'll just assume you've reinvented the martingale strategy.
