Which Alt-Coins Should Be Mined?
If you had started mining Bitcoins back in 2009, you could have earned thousands of dollars by now.
At the same time, there are plenty of ways you could have lost money, too. Bitcoins are
not a good choice for beginning miners who work on a small scale. The
current up-front investment and maintenance costs, not to mention the
sheer mathematical difficulty of the process, just doesn't make it
profitable for consumer-level hardware. Now, Bitcoin mining is reserved
for large-scale operations only.
