To briefly explain Nicehash mining, the program you download scans your system, digs which cards you see and which coin is the most profitable. He pays for the coins he digs in Bitcoin.

Basically, NiceHash connects buyers of hashing power and sellers of hashing power (miners). NiceHash is the most profitable way to mine because the buyers are constantly fighting for the hashrate that sellers provide on the open marketplace.
So,to me it seems profitable.

Yes it will be profitable because it has the largest hash-power broker marketplace that connects sellers or miners of hash power with buyers of hash power. Hash power is a computational resource that describes the power that your computer or hardware uses to run and solve different cryptocurrency Proof-of-Work hashing algorithms. NiceHash service is unique in a way that only connects different end-users and is not offering any cloud mining options - meaning NiceHash does not own or rent out any mining equipment.
Nicehash is an auto-switching mechanism, which picks the most profitable algorithm to mine at any given moment. Meaning that you do not need to worry about switching between different coins like Ethereum, Beam, Grin, etc. The buyers pick what coin they want to mine with the hash-power they bought. Therefore a seller of hash-power is not burdened by picking the most profitable coin, buyers do that for them.

Get started with:
There are three requirements you need to meet to start mining at NiceHash:

You need strong enough hardware. You can check supported hardware here,
You need a Bitcoin wallet address (You can get one by creating a NiceHash account),
You need software for mining (NiceHash Miner)

First thing you do is watch some video in youtube regarding nicehash.

Currently, it is better to mine on Kryptex - keep the link https://www.kryptex.org/?ref=8b072219

Another question that has recently become popular in the crypto money industry is the question of what is cloud mining. In this article, we will give you some information about what cloud mining processes are. As is known, cloud mining allows you to easily mine using a remote data center, without directly using computer power. This way you don't need to have any mining equipment or anything extra.

NiceHash is based on the concept of a sharing economy by connecting sellers and buyers of computing power from all over the world.
You can start by registering at NiceHash
The most interesting and practical of NiceHash is that its platform allows you to interact in two ways; the first being a buyer, you can request the mining services of other platforms or algorithms offered by different vendors, which makes a significant savings to the buyer, since it does not require capital investment in mining hardware. You simply rent the "hashing" computing power of your online platform.
If you own a computer or a mining rig and want to use CPUs and GPUs for mining, All you need to do is download NiceHash Miner, set it up, and let it run.

NiceHash is an open marketplace that connects sellers or miners of hashing power with buyers of hashing power. Buyers select the crypto-currency that they want to mine, a pool on which they want to mine, set the price that they are willing to pay for it, and place the order. This order is then forwarded to everyone who is connected to NiceHash with NiceHash Miner or other mining hardware (like ASICs). Your provided computing power will fulfil the buyers order and you get paid for this service.

Yes, you can start profitable
