When it comes to cryptocurrency, there are two phrases that come to mind. The first phrase is this, “Two roads diverged in the woods, I took the one less traveled by.” The second phrase is, “Always take the path of least resistance.” These phrases are the basis of real earnings.
The real fact of the matter is there are no real experts in cryptocurrency. They always seem to not really get it quite right. Another thing you should ask yourself is this,“Why would you take a new system, and do the old system on it?”
With that information out of the way let us show you real facts you can understand. The term difficulty is the only thing you need to concern yourself with. If you can trade the coin then you should never listen to those people who do not fully understand the concept. The first thing you need to look at is share difficulty.
SHARE DIFFICULTY
Share difficulty is the difficulty it takes to earn a share on a peer to peer pool. If you look at the image below, you will see that this particular script coin has a difficulty based on a cpu.

This means that it is far easier with a L3 to earn shares. You are only paid by accepted shares. This pool will produce faster shares because the math problem involved will be far less difficult than mining Litecoin. Now let us take the second, which will be the Network Block difficulty.
NETWORK BLOCK DIFFICULTY.
The Network Block Difficulty is the difficulty of the math problem your miner will need to solve in order to get the block. If you look at the image below you will see that the Network Block Difficulty is far less than an Antminer L3.

You will notice that the difficulty of the math problem is equivalent to a GPU mining rig. This means you can earn more coins in a faster amount of time.
When it comes to earning money with mining, always remember to listen to nobody. They will guide you right to the higher difficulty coins and you will not get much. As long as the coin can be traded, it is fair game and you should mine it. These people are earning approximately a little over one-dollar a day because their miners can not handle the difficulty. That is not good for business. You are mining to make a profit. You need to start learning what really works for you.
I hope this little insight into the actual mechanics of mining works for you. Remember the less difficulty the more you will earn. There are several coins that you can choose from that can be traded. Do not ever get discouraged, once you see more money coming into your wallet, you will fully understand what works for you.
