I looked at the last 6 or 7 months, and yes some months are better some are worse, just a totally rough estimate, I'd say the site brings in an average of 90 BTC's profit a month. (If im wrong, correct me). So each month really you are getting about 0.27BTCs, But even if its double that, and each month you get 0.5BTC, to even get your money back, and break even would take over a year at 7.5 BTC's. And like the guy said in the previous post, the whole economy of bitcoins in general is so volatile.
So lets say the world figures out bitcoins are the best, it gains popularity, and doubles in value, then it would only take 8 months to break even?
So all that happens, its very lucky, you wait the 8 months, and finally you can get your 0.4 Bitcoins each month? I feel like it might be easier to just throw a bet at satoshi
What does doubling in value have to do with anything?
You buy in at 10 BTC when BTC is $100 each. You spent $1000.
You sell out at 5 BTC when BTC is $500 each. You make $2500, or $1500 profit.
BUT you could have kept the 10 BTC and now you'd have 10 BTC at $500 BTC each, worth $5000, or a profit of $4900.
Which was the better deal?
Tl;dr: the price of bitcoin should NEVER be taken into consideration when dealing with a BTC-denominated 'stock.'
