There’re other reasons why Bitcoin mining is so difficult. Nowadays most of all BTC miners are located in China where they use cheap energy on enormously large mining farms. That’s why other miners have low chances to get rewards. Chinese systems are really huge and efficient. The only way I see is trying cloud mining and grabbing a lot of BTC bonuses to lower deposits and increase ROI. You can find bonuses on cloud sites like Hashflare and Genesis Mining or check specific projects dedicated to these campaigns like http://ccgminingcode.com/ for CCG. Surely, mining altcoins is a solid way to make money but Bitcoin is the main currency, so it’s better to have some.

Well, you can start with cloud mining. Just mind that it’s quite risky investment, so it’s important to trust only reliable services. If you are ETH miner, check the guide: http://miningtop10.com/ethereum-cloud-mining/. Following by this link, you can find cloud mining sites which have great audience and some proofs of reliability. It doesn’t mean that you will get mind-blowing ROI, but I think it worth trying.

Of course, there are some apps and services which let users mine with smartphones. But they are even more unprofitable than web or CPU mining. Lol, they even lose in comparison with cloud mining which has relatively low but still possible profits. So, my advice is to forget about mobile mining and switch to regular hardware GPU/ASIC mining or cloud mining (for the latter option, check the list of trusted sites: http://miningtop10.com/ ).

Which coins are old? If you’re talking about Bitcoin, Ethereum and other major currencies which originated a few years ago, it’s not the worst way. Bitcoin is controlled by large mining pools but other old altcoins are reliable, so they can bring more money in the long run. With new coins, you can’t be sure about their future. Additionally, new coins aren’t supported by large cloud mining sites. If you prefer this way to traditional one, focus on old altcoins. what’s more cool, you can get bonuses which aren’t available for new tokens: http://ccgminingcode.com/ . However, you should always consider risks of both cloud and traditional mining. Trading and investing may suit your style more.

It’s the first time I see someone mining with smartphone. It’s odd. Don’t get me wrong, you can mine with phone but it will be completely unprofitable, you will not earn even a hundred dollars per year. Phones aren’t designed for mining. If you don’t have equipment like CPUs or GPUs, consider joining cloud mining sites. They require nothing but money to pay for data plan. With such services, you use remote hardware to mine crypto. Also, they offer bonus codes regularly, check this link for instance: http://hashflarecode.com/. There are several coins available. The most important thing is to trust only famous old sites with huge audience and don’t invest in scam examples.

I wonder why you didn’t include info about cloud mining as it’s also an option to get some Litecoins. Many newcomers can’t afford expensive equipment for traditional mining, so cloud may be an interesting alternative. Just as example, large cloud services offer various bonuses regularly (like this http://hashflarecode.com/). It would be better to write a few sentences about cloud sites, so visitors will be able to compare different options.
