Just wondering if anyone here uses bitcoin? I was surprised to see a lot less gui clients for mining bitcoins than I would have thought for linux. Anyone here using any bitcoin miner in particular?

I got interested in bitcoin about a year ago and since then have been playing with various software and mining setups, starting with diablominer and cgminer and currently bfgminer, bitcoind / bitcoin-qt and p2pool. All of this on Slackware, of course (buildscripts and packages available on request).

I don't see much point in using a GUI miner because there's very little to set up (pool address, username, password) and no user interaction once the miner is running. A console miner is easier to monitor (ASCII log file) and can be run on a headless system without any effort.

Are you aware that mining bitcoin on GPUs is now not profitible?

GPU mining certainly is NOT profitable, can be an interesting experiment though, e.g. when you employ PCI-E passtrough to make use of the GPU in a virtual machine because you don't want to poison your system with the Catalyst drivers (done with Slackware64 14.0 and qemu).

A 5$ second hand USB Block Erupter might be a more sensible option if you want to study how bfgminer, p2pool and bitcoind work together, without getting ruined by the energy bill. Don't expect any profits, either.

To get back to the topic: it's easy to build and run bfgminer, cgminer or diablominer on Slackware. How well it works depends very much on the type of hardware you're using. In either case, bitcoin is no magic money making machine - calculate carefully! Getting it all up and running can be fun, though, even if it's not profitable.

I still use 14.2. Is it possible to compile bitcoin slackbuild without Qt5? I am going to use only the command line interface and don't need GUI.

There is no reason to use today the Slackware 14.2 unless you run some kind of server.

Heck, even Slackware 15.0 started to look old.

You speak for other people? Are you god?

What makes you to believe that "I speak for other people" ? So, saying "man, it's long overdue to upgrade you system!" is demanding?

And no, I am not a god, neither you are. Both we are mere mortals - at least that's what I guess, I do not exclude that maybe you are an AI.

But how you are wiser than me, please show me a single reason to use even today this Slackware 14.2 on a desktop or home computer (as you seen, already I have do not excluded the server usage) . I for one, I see no one.
