I was considering buying about 75GH/s for about $900 off ebay...
But you say what if BTC goes to $10,00 by May? Well I will have accumulated $7400 minus the $900 on equip plus electricity and fees. Thus netting me just over ~$6300.
What if you buy bitcoin with your $900 budget now, you can get ~1.2 bitcoin (~$750 on bitstamp atm).
And if BTC goes to $10,000 (your $10,00 was a typo it seems), you will get yourself $12,000 (much better than 6500 minus electricity fee).
No offense, but if your mining profitability comes from the expected uprising bitcoin price, then you should just buy btc directly and forget about mining.
And don't take me wrong, mining is fun and I really enjoy my experience with mining.
Unless you are one of the ASIC mining developer. Then you can stay ahead of the curve by doing the preorder garbage they do.
I do believe it is still possible to profit mining new coins.
Yup, it is very profitable to sell (or scam
) pre-orders, and mining scrypt-based coins is still profitable now.
