Here are some good reasons to mine Monero:
Mining can be a great way to subsidize the purchase of a new top-class GPU.
Monero is easily traded for bitcoin (BTC). This is an inexpensive way to multiply Bitcoin.
BTC can be easily sold at good prices, so mining XMR can be a good way to indirectly fill your bank account or get cash. XMR can also be sold directly on several exchanges.
Mining can be a cheap entry ticket to the XMR market, because it is loved by traders because of its high volatility. If you are a good or lucky trader, you can maximize your profits - especially if you buy prices on a large scale in Monero.
Since XMR has been attracted to the black market in 2016, this is already one of the highest altcoin prices on the market.
XMR Mining, which is based on the CryptoNote algorithm, uses less electricity than Ethash Dagger Hashimoto coins (Ethereum, Ethereum Classic, UBQ) and Equihash coins (Zcash, Zencash, Hush). This can cause lower temperatures when heat output is a concern (yes, I also installed too many cards in a closed place!) And also have to contribute to a longer GPU card cycle.
