The problem with these questions is that they are rather vague. It is like asking, "shall I buy a blue winter coat"? If we don't know whether you live in Antarctica or southern Italy, then we cannot answer you.
Your income and rate of return depend on a lot of factors, such as
- Investment cost
- Electricity price
- Hashing speed
- Price of Bitcoin
- Mining difficulty
The Bitcoin price is a huge factor that one cannot forecast. Hence you can only tell how much you would make with X amount of hashing power right now.
Specifically with cryptocurrencies it is hard to tell whether you will be able to make a profit. This is partially, because one would have to define profit. You may not make profit if you immediately convert all coins to fiat, however in case the price of BTC rises, you may be lucky and have a quick return on your investment. Hence if you have some capital to invest and you are willing to gamble on bitcoin, then you can mine and hold whatever you get.
If you are looking for a hobby activity the train may have already passed. However, if you do have access to cheap electricity (in some countries this is not a problem) you can have some fun and some profit as well, provided you sell your miner at the end of the whole process to get back something on that as well. If you are truly interested, give some idea on what you had in mind. Capital you are willing to invest, hashing power, electricity prices.
One thing is for sure, running some mining will teach you things bout bitcoin in general, computing etc, and in the worst case scenario (aka if you haven't done your research on the topic) the fact that it is not worth it.
Regarding cloudminingThey have a business profile of buying hardware, selling it in small chunks for a larger price, making users pay the hardware depreciation cost under the terms of "maintenance, hosting, electricity" and then possibly repeating the whole stuff. They make profit, but your profits reduce gradually.
I had a few shares on XY cloudmining service. The maintenance fee was approaching my income and at a point it reached it, meaning I was getting 0 coins. However, I paid for the company for this share, so they were OK, they got their money for the hardware, got return on investment. Then I stopped getting payouts, but I doubt they stopped the farm hashing for them. They got their initial investment back and are probably running the hardware until it crashes.
If the deal is realistic, you won't make much if anything at all. If the deal is too good, you won't make much and you will lose your investment (aka scam). If you find a site, make some research on it and see if others have confirmed it.
