I want to mine Bitcoins or Altcoins

Im a noob and I start from scratch.
Waht do I need and spend to make at least 100$ from mining per day??

right now you need 400gh/s to earn $100/day or 0.1btc/day.
and after next difficulty jump in 10 days you will be earning 25-30% less.
I don't know if you are aware of that.
it's not constant same amount earnings.
anyway, you can buy few of these

forget about gpu rigs and scrypt coin mining.

ok thats high

what can I expect using those asic miners that are 333MH/sec if I mine Lite cois or PPC coins??

and what are the minimum system requiremts to run an asic miner effeciaently??

[vpasic]

you can't expect anything.
330Mh is so low that there is no point mining with it even if you get it for free.
to show you how pointless it is, I have 3x60GH/s BFL and with 180GH I can earn 0.05BTC/day.1
180GH compared to 0.333GH!!! absurd to even try to mine with it.
second thing you can't mine LTC with asic. asic can mine only sha-256 coins.
also there is no point of mining ppc or any other sha-256 coin since btc is most profitable.

there is no minimum system requirements for pc used for running asic miner.
any computer will do the job since you are not mining with it, you are mining with asic miner and computer is there only to run mining software.
 also newer asic miners are standalone miners. they have mining software installed inside so the only need to be connected to router.

I have a few rigs (scrypt coins based on 3 x GPUs : 2000Mhs each)and a new bitcoin miner (30GHs)

When I started I thought I would make money, and was considering starting a business around it.

Now I've got a bit of experience, I am much more interested in this as a hobby and to support the network.
I may not make my investment money back (I've covered about 30% of my costs so far over the last 2-3 months so fully expect to end up out of pocket)

If you want to make money, and believe in bitcoin/cryptocurrency, then you're better off just investing in the currency (ie buy bitcoins)
If you want to start a new (expensive) hobby, then get into mining. Scrypt or SHA256 doesn't matter - its not a money making investment.

Now I've done both, once you know what you are doing, bitcoining mining with standalone cubes is much more reliable and easy to set up than scrypt mining with milkcrate rigs.

My rigs give me periodic grief

If your on a budget, Your best bet is going with scrypt coins such as litecoins and DOGEcoins etc.

You can mine those coins on your CPU and Graphics Card, or both at the same time. Do not buy anything used as its way overpiced, even for those popular fast BTC miners, people tend to be greedy and its their gain, Your loss, Because you will have a ROI in 3 months.

So, Its all to a matter of preference.

What do you think, will cryptocur-producers change algoritm when mass srypt-miners appear? Or there is no other algos except sha256 and scrypt?

[vpasic]

don't think so.
you really think they will made up some XY coin with XY algorithm just to save gpu-s and keep them in the mining game??? don't think so!
future is in new technologies, not in old ones!

Don't get into mining to make a lot of money or you're going to get burned. Just flat out buy the Bitcoins.

Agree.
Just buy bitcoin/litecoin directly.

While I'm not against buying into alts, like Litecoin, I'd suggest that if you're "playing it safe" you still avoid that as well. Anything that introduces a new failure point is bad.

You need to learn more about difficulty and understand about mining first...
