It's too late too start mining. Don't waste your money! By the time you get your mining machines the hash rate will be so high that it wouldn't be profitable to mine.Look up the chart for how fast the hash rate is increasing http://blockchain.info/charts/hash-rate
The hash-rate has been going up very rapidly for mining bitcoins. Why have people been buying ASIC mining machines if the machines are going to obsolete and completely useless in a couple months to a year?
There is no point to get your dad into bitcoin. If you like bitcoin then you should invest in it because YOU believe in it-don't drag your dad into something that he doesn't understand nor wants to invest in.
I have been monitoring bitcoin after the price of the currency collapsed from over $200 per coin. After the collapse I thought that the price would stay steady at around $100, however, this is not the case-it has gone down to about $84 currently.I believe that a currency cannot have such fluctuation for it to succeed What is the reason for this drop from $100 to $84?
