why bitcoin mining difficulty is increased?

I just want to knows that why the bitcoin mining difficulty level is increased and i am afraid of the life of future miners.Maybe in future the miners electricity will cost more than our rewards because of the difficulty level.

3  Bitcoin / Group buys / 300x Avalon 6 group buy on: November 29, 2016, 05:41:06 PM
Hi All,
 
on the goods forum there is a topic of yxt selling approx 300 Avalons A6 https://bitcointalk.org/index.php?topic=1680392.0

Since he doesn't want to sell individually, I was thinking of organizing a group buy.

First I want to see if there is enough interest to negotiate a good price.
I have made a google form to check the interest, please view it here: https://docs.google.com/forms/d/e/1FAIpQLSfg3xrmsq4UCTcZp4JeSg3aRUmA5kR9F48Mke--Y8ByZYod1w/viewform

How does this work?
a group buy with a variable price is quite difficult, so here is the idea.
People give their interest at a certain price point. After that a calculation is made (by me) what the total revenue is, when the top 300 offers are included. These people get a offer with their price/quantity so that the whole lot is bought.

A simple example
lets say there are 10 units available.
A offers 2@220, 5@210 and 10@200
B offers 2@230, 6@220 and 10@205

B will get 6 units @220 and A will get 4 units @210

Notes
  • Please fill in the cumulatieve interest, If you want 10 for 220, or 15 for 210, please fill in 10 and 15 in the fields
  • Prices excluding shipping, see postnl.nl or deutschepost.de for shipping rates
  • Prices exclude the Raspberry to control the miners
  • PSU's are not included. I might be able to fix 90%+ PSU if the quantity is right


The global planning

  • Check intrest
  • Negotiate price
  • make offers towards all interested
  • Find escrow
  • Collect money
  • farm visit (preferably with escrow)
  • Buy
  • Ship

If you have any questions, feel free to ask!

10  Economy / Services / Looking for resellers on: February 29, 2016, 10:20:29 PM
Hi All,

The past two years I've sold around 200 PSU's to miners here in The Netherlands.

What I realized is that there is no decent website to order server PSU's in the EU, so I opened one!

you an visit it here: http://www.bitcoinpsu.eu/


I have recently bought a large batch of power supplies. So big that I can't sell it on my own.. For that reason I'm looking for a couple of resellers of my PSU's.

If you're interested, please have a look here: http://www.bitcoinpsu.eu/reseller.html

Regards,

Burks
