Hashrate versus Mining Difficulty.

Hashrate
Hashrate simply means the speed at which the outputs are computed per second.

This  hashrate is measured in H/S ( harsh per second ). That means the speed at which the computer or mining equipment mines output in the blockchain per second.

The mining equipment used can be either be GPU (graphic processing unit) and CPU(central processing unit). GPU has a high H/s which  increases the probability of profitability of the miner while CPU has a low H/s which decrease the probability of profitability of the miner.

Mining Difficulty
This is how hard it is to mine a block to add to the blockchain network.

From my research, I've been made to understand that hashrate affect the mining difficulty. Low hashrate increases the difficulty while high hashrate decreases the difficulty of mining.

• s it true that GPU can increase the hashrate? If yes in what ways?
  
  
• How does mining difficulty be reduced?
• Are mining difficulties of all crypto the different, I suppose yes, but I need further enlightenment about such differences.

Nope,

First of all, don't mine bitcoin with a CPU or a GPU, only latest gen ASIC's.

Secondly, your own hashrate has very little impact on the difficulty. The difficulty is network-wide and is based on the average time between the blocks during the previous retarget period.
If the combined hashrate of all miners goes up, the average time between the blocks should go down, and during the next retarget the difficulty should go up to make sure the average time between 2 blocks is once again ~10 minutes.


I have no idear what you mean... A cpu can create x sha256d hashes/s, a gpu y hashes/s and an asic z hashes/s
x<y<z

The difficulty will ONLY be reduced at the next retarget, and ONLY if the average time between the block during the last 2016 blocks was > 10 minutes. If you want a lower difficulty, you'll probably have to bribe big miners to turn off all their ASIC's?


yes, what is there to say... They all have their own blockchain, so there is no relation between a block found on the bitcoin network and one on the litecoin network (for example), so they each have an average time between their blocks, and a different difficulty

I recommend that you read a lot more before you start posting stuff like that. It's all wrong.

Thanks for the constructive criticism. What specific explanation can you poont to be wrong? In fact, what do you mean by ' it's all wrong.'

Show me and I'll take corrections but your comment is hard and vague to understand.

My point is that you appear to understand less than you think. It would be ore helpful to others if you could understand more before trying to explain it to others.
