I'm Considering Bitcoin Mining

Cost of electricity can be controlled with solar panels. Make sure to have powerful pcs as it will take a while to make your investment back.

The real risk, at least for BTC, is that it's just not efficient for you and that your'e likely to spend more money on electricity.

1. Back in the day, you could use CPU's
2. People switched to GPU's, and for some currencies / price levels it makes sense
3. Now, people have dedicated ASIC's

In short, it's not super efficient by any means.

Further, some currencies are moving away from PoW (proof-of-work).

Mining is profit in any case, only the cost recovery depends on the rate, the lower the bitcoin rate, the longer you will go to payback

Because you can earn very fast money, in this time it is not so much indeed. Thats why you need to start when it goes hard.

You'll be going up against some big players who've been around a lot longer than you with million dollar mining farms. So it would be a lot harder to mine profitably. Why don't you sell something for btc!

It is kinda failure idea because electricity costs much more

What are the major risks and challenges of bitcoin mining, if any, or is it just all profits once setup.

the bitcoins are less ... how should I say ... okay, you know it very well!

I don't know much about it, but I think it consumes a ton of electricity.

Not worth to do that cost too much afford then profit that make, better do trading instead
