Why is there a nearly $100 price difference between BTC prices at Mt. Gox and Coinbase? Ignorant question: If this price difference exists why can't I just buy BTC all day at one exchange and sell it at the higher priced exchange? I'm new so please just assume ignorance on my part. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

@mpattison I'm new and ignorant. Please correct me. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

@nodroids So you need a full scale commercial setup for mining to be profitable with SHA256 coins? Does the same logic apply to Scrypt coins?

Op is back. Coinbase is clearly the winner for a noob like me. I signed up on 1/4/2014 (Saturday) and I was fully verified (bank account, credit cards, etc.) by Tuesday 1/7/2014. I bought my first BTC this evening (0.05 BTC). I originally signed up at Mt. Gox on 11/29/2013 and after several emails to support, I was finally verified yesterday, 1/7/2014. Mt. Gox took 39 days. ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Coinbase took 3 days. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Thanks to everyone for your helpful suggestions.

With all the rapid changes in ASIC mining capacity and mining difficulty, is mining SHA-256 coins a speculative venture? In other words, you mine and hope the coins rise in value?
I am new and probably ignorant of the facts, so maybe that is how mining has always been.

Is it possible to regularly remove coins from a wallet and place them in a separate wallet, then move the wallet to encrypted physical media, then put into a safety deposit box at a bank?
Yeah, I'm paranoid as hell, but I'd rather have a several safety deposit boxes full of encrypted media, than an empty wallet.

Thanks Amph. I guess without any scrypt ASIC chips, hash power is limited to the maximum GPU of the day.

So everyone's activity is divisible by 14? With the exception of new people.

Anyone...? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)

OP here to follow-up. Coinbase could not be any simpler. I wish I would have signed up here in November instead of Mt. Gox. I am still waiting on Mt. Gox to verify. When they finally verify I will write a follow-up to compare how long it takes to sign up at Mt. Gox vs Coinbase.

What are the MH/s ratings for the most power Scrypt miners available to individuals? Do GH/s machines even exist for mining Scrypt?

I am a computer programmer, but I haven't built my own machine in 10 years. I see that people are moving to milk crate/PVC pipe cases and am not even sure where to start or why I would want to do that. I know that I would want 4 - 5 GPUs, but I have no idea what type I should get.

Its hard to say long term. I built my miners not just for the coins, but for the fun of it too. I love computers. When coins are launched, they are not on an exchange so its hard to buy unless you can find private sales. So mining gives you a head start. Mining is also how transactions are confirmed so they are crucial to the whole thing, if you believe in the concept, build a rig and contribute some hashes. If it all goes to sht, you can always build a gaming rig from it all or sell it off at maybe 50% of what you paid.
I guess that means you should mine several coins as a hedge against risk.

How much time elapsed between signing up at Coinbase and buying for first BTC?
|
|
|
Does it make economic sense to buy these miners at today's prices or are you buying them, mining and hoping the price goes up?
|
|
|
How many khash/s do you expect do you expect to get out of this rig? What is your budget?
|
|

At current prices, are there any alt-coins that are worth mining, instead of just buying them from an exchange? I am curious about Scrypt, SHA256, or CPU-only coins.
Is mining a speculative investment? I am new, so this is not fully obvious to me.
