this could be a great thing for sure..
but i think you are doing so because in your country, the energy cost is under or near 0.10$.
i give you some example:

S9 last batch 14THASH price is about 2100$, consume about 1500watt at the wall, 0.10$ watt/hour
Days to generate one BTC: 141.93 Day(s) (can vary greatly depending on the current exchange rates)
Days to break even: 544.14 Day(s) (can vary greatly depending on the current exchange rates)

just if you double energy cost to 0.20$ you get:
Days to generate one BTC: 141.93 Day(s) (can vary greatly depending on the current exchange rates)
Days to break even: 8098.30 Day(s) (can vary greatly depending on the current exchange rates)   

You're right. It is best to avoid gambling. They can not lead to anything good. I myself was fond of it once. Then I realized that I would not earn anything.
Now I get bitcoin in other ways, more reliable and easy

Great way to make Bitcoin in my opinion is to trade bitcoin.

Although sometimes slow, but sometimes in one day can make a profit of up to 30%.

Very precisely. To get the bitcoin, we can use a lot. From the start by following the sign campaign in forums, social media, advertising advertising newsletter, Faucet, PTC, gambling, investing, and much more. Because bitcoin also has many branches, so we are not just glued in one way. So, before stepping to get bitcoin then you must equip yourself with basic knowledge of bitcoin
 

In my opinion, best way only mining for make bitcoin. Else other ways very risky or very inefficient and not effective.

I couldn't find better alternative for make bitcoin.

Yes it's if we are have more capital, But if we dont have capital, I guees the great way
to make Bitcoin is by signature campaign and seeking any bounties in this forum. It's Free friend 

I agree with that. I tried some of the threads to which they post how much equipment things are and they are really expensive. This is just for the capital so you would need to get ROI after that. But the next problem would be the electricity. It really takes a lot of it and can you earn bitcoin that will be higher to what you will pay monthly. I think there will be not much room for profit with that.

Save your money and when bitcoin price  is drop  buy bitcoin when wait till bitcoin price has good price and sell your bitcoin and wait again till bitcoin price is suitable for to buy i m trying to do it and i make some price in my mind and when the time come i buy and i sell my bitcoins . I think it is good way to make more mitcoin for me.

I also like this way because currently fluctuation is very quickly happening but if you have small amount then you can stuck because if its gone down after your buy then you have to wait for rise until your recovery otherwise you can lost some good amount in this fluctuation
