1) 2.5 BTC per share -> 0.036 weekly dividend = 0.145 btc a month = 17 month breakeven
2) 50 BTC (20 shares) = 3 btc a month
3) 50 BTC buys you a 13 GH asic card = 12 BTC a month (factor in whatever difficulty increase it is still significantly better income, and keep in mind the mining shares dividend are also impacted by the difficulty increase).
So i really dont understand why anyone will buy asic shares? what is the point? the return on those are terrible, on top of absolutely insane counterparty risk dependent on some guy who is running a black box that tells you what dividend he will pay.
Why would you not just have a physical card you own with no dependency on third party and make significantly more btc as income? Yet so many smart people are buying those shares...there must be something i am missing?
waiting to be enlightened...
Your looking at this completely wrong. Your comparing apples and oranges. When you buy shares of a company on the stock market, I dont know anyone that asks how long until the dividends completely repay the investment 100%. The shares alone hold the value.
You are not considering the capital appreciation if the share prices rises, which it most likely will. At any time you can sell back the shares and get the initial investment (and more) back so you dont have to sweat "breaking even"
For a piece of hardware however you do look at it that way... You want to know how long until you repay the initial investment because you are not able to sell the hardware down the line at the price you paid for it. 13 gh a month does not get 12 BTC either. The way that hashing is increasing, you will be lucky to break even in a year.
