I'm aware of all of this. I actually have a mining setup doing a measly 15 gh/s or so out of some mixed stuff. I like the hands on aspect of it.
I also have a cex.io account too.
We also have free electricity as a bonus. We have a methane electricity generation plant on the family farm here. It just went online this summer.
One of the best things for me with this is I am recently disabled it gives me something to do. I got hurt with some logs 1 1/2 yrs ago and just had my 2nd surgery two months ago and today in fact a freaking spinal myelogram today which was horrible and I had just thought I was getting a CT scan to see if the scar tissue or SCS implant were what has been causing problems.
This gives me something to have fun with.
I was a Systems Admin/Network Tech for the last 18yrs. I cannot do that anymore but the tinkering here and there when I am able keep me from going nuts.
I was healthy, fit, happy and active and in a split second it all was gone.
Sorry for rambling on I just enjoy this. I can mess with them from bed and learn the differing programs and such.
It's fascinating and fun.
I don't have any extra money usually but the bills are paid. With this I was hoping to buy something more to play with and learn.
I also want to have lightfoot speed up my jalapeno.
With the bit of coin I made I have just got another redfury to play with it should be here soon too.
Hopefully I can get some ideas from you all.
You can buy cloud mining power at cex.io
I don't suggest you to use this website in order to invest! You could buy just 1 GH/s just to understand how mining works and get the feeling of mining bitcoin on your own.
But honestly buying a miner you're going to run on your own is a bad idea. Besides all the fuss and the bad experience you can have with the companies that sell them; we're also just a week before the next difficulty reset which is going to be one of the biggest resets if not the biggest (30%). According to that, putting your money to a miner would be a bad investment right now or at any time since we're at a point that there's no getting back now.The difficulty will just keep going up.
Here's my source for the info about the reset:
