I am planning to build a mining tool in my home. but before I do that.
I want to know some of the biggest problems in mining.
Would you guys tell me about that?

Do you mean you're going to build your own ASIC, or are you planning on setting up a mining farm by yourself?
In the second case, the number one reason people don't make any profit is the power cost... If you want to make some profit, it's best if you pay 5-10 cents/Kwu (the lower the cost, the better offcourse). At higher power costs, you might still be able to make some profit mining altcoins, but chances of ROI'in in a reasonable timeframe while mining BTC are getting rather low at these prices

Sorry in advance I am not clear to convey my point.
Thank you for advising and your advice I am very understanding.
How would you advice me, should I mine using ASIC or mine altcoin using Graphic Cards (RIG)? are they the same?

they're not the same

To be honest, i used to mine BTC, but i've never gotten into altcoin mining, so my advice might not be 100% correct.
In my personal opinion, BTC mining is more predictable... You know which coin you'll mine (BTC), you can more or less make an educated guess about the diff and price fluctuations (but like i said: it's an educated guess, strange things CAN happen to the BTC network's diff and BTC price in a short period of time). Given your power price, the ASIC's specs and your educated guesses about diff and price, you can more or less try to predict your ROI. With this ROI you can more or less predict if investing in an ASIC is a smart thing to do or not.

Compare this to altcoin mining: in my opinion, the altcoin prices are coupled to BTC (making their FIAT price fluctuate a lot more than BTC's), their diff fluctuates a lot more, new algorithms hit the market all the time... This makes altcoin mining, in my opinion, less predictable. It does mean, however, if you keep monitoring the altcoin mining scene and constantly adjust what you're mining, you might make a lot more profit if you know what you're doing.

A second thing to realise is that GPU's have a much longer guarantee period (a GPU can be under guarantee for 2-3 years, while most ASIC's have a guarantee period of only 90 days).

A thirth thing which might be nice to know is that, generally speaking, the resale value of GPU's is much higher than the resale value of used, older ASIC's. I might be mistaking here, but i also think GPU's don't get outdated as fast as ASIC's...

I will think again. But thank you for giving me feedback. Really very useful information for beginners like me.
