I 'm not sure what you mean exactly. After all it's not like miners will to take away electricity from the rest of the world just to power their machines 

I 'm worrying most about bitcoin clients that look like software from the 80's. 

I wonder how hard is for engineers to tear a chip apart and find out if indeed there is some backdoor of any kind 

Even if it goes up, is there any real reason for that? There are way to many concerns around quark 
It's community though did a very well job in promoting it.

It's hard to find profitable options for mining equipment. Your math are good but you should do your calculations based on how many bitcoins you can buy instead of the mining equipment.

Bitpay runs a nice catalog of businesses accepting bitcoin. I guess your site should be already there.

The only problem here is that you should trust the guy issuing the options.
You don't want the site to get "hacked" or something during a huge price dip 

Both the alts that you mentioned are among those that have the higher chances to succeed. Litecoin is already an established alt coin with a solid user base and a strong network and peercoin offers some genuine features over bitcoin like proof of stake.

If difficulty keeps doubling for the next 14 months i think the price will be through the roof. So we are not exactly fucked  

It depends on what the groupbuy is for. Usually groupbuys are for preorders and preorders are risky and with the products coming many months later.

I have yet to see a cloud mining service where you can actually profit. People soon realize that they have to spam referrals to make up for the bad deal 

If you don't care about electricity cost then it won't hurt you to try and mine some altcoins. Download cudaminer to max your results for the nvidias.

Seasonal coins give a new meaning to pump and dump. Why not santacoin anyway?

Those capchtas are the single most annoying part on the internet. 

If the same shortage applies to nvidias then litecoin has probably nothing to do with that. But if nvidia's are still available for sale then mining might have something to do with it.
Also don't forget that an average gamer buys 1 gpu while an average miner buys a lot more.

I have a suggestion. The stopmakingcoins coin. SMC.  

You think that people are ready to buy only days after bitcoin lost half of its value?
It 'll take time for confidence to be restored.

Actually i 've done that already but only tried it a few times just to get a feeling but with the "try it without installing" option
I 'm not sure that i noticed a persistence option. I 'll check again.

I didn't missed it, it's just that saying "solid exit strategy", sorry i mean "solid EXIT STRATEGY" doesn't mean anything.
Except if you want to share some solid EXIT STRATGies with us.. 

Ok thanks for your answers everyone. I think i 'll go through the learning curve and try linux sometime soon. I mean with bitcoins close to 1000$ i 'll need as much security as i can get
