Depends what you want to do.

If you are asking in terms of making money right away, definitely buying is the answer.  If you are asking because Cryptocurrencies interest you, and you want to really feel apart of it, and making money doesn't matter, then mining is the way to go.

If you choose to mine, you will need to put a lot of money up front, that you probably won't make back for at least 5-6 months.  Up shot is if the difficulty doesn't increase much in that time, you can continue to make more coins then you could have purchased right away.  The bad side, if you choose to mine, and another ASIC wave comes through (Next Gen ASIC's launch), you may not even make back what you originally purchased your mining rig for. 

Anyways to answer your questions.

1)  A GPU is a fancy way of saying a Video Card.  You can purchase one at any computer store.  But the better ones are usually located online, or specialty computer stores.  Don't go to Best Buy and expect to see a really good Video card sitting on the shelves.

2) A decent card is probably going to cost you $400-$700 each.  Due to the questions you are asking, I wouldn't recommend going above 1 card for now, until you know what you are doing.  And actually if your planning on spending quite a bit, I would recommend purchasing an ASIC miner, then trying to make a large GPU miner.  If you need to ask what a GPU is, you really aren't ready to put together a multi GPU mining rig.

3) Not sure what you mean, but you will need to make sure you have a large enough power supply for your unit.  With a 1 GPU unit, a 600 W unit should be enough, once you go bigger, the Power Supply needs will start going up a lot.

4)  No idea, but if you know how to do this, you could become a millionaire without needing to mine.  Unless you plan on running a cord from your neighbors house to yours to plug in your miner.  (PS  you better not be my neighbor)

5) I really don't recommend you do any CPU mining.  There might be a coin or 2 out there yet that you can CPU mine, but probably not worth it.

6)  Yes ASIC mining, or in your case, you might want to look into Cloud mining.  A lot of them are questionable.  I can recommend the one in my signature or click here:  https://Micro-btc.com/?r=Vivisector999  as I use that one for some extra mining.  I think it's legit, but you never can tell.  If you click on my link and sign up, you will get a small fraction of a cloud miner as your own, which will mine for you for free.  If you want to it to mine faster, you will need to put some money into it though, like I have.

7)  That one is very random.  Basically the bigger you want to get the more you can potentially make.  If you spend $1000 you aren't going to become a millionaire by mining.  Mining is more a for the love of mining thing than a big money maker.  I can usually make more trading coins in a single trade than I make mining all day.  Some spend $20 purchasing some cloud mining.  Others spend $100,000 or maybe even a $1 million buying large ASIC miners to actually make some money.  With mining it takes money to make money.  But only do what you are comfortable with.

8 ) Cool  No harm no???  A GPU miner is not really that much different than running a computer in your house.  There are at least 2 main factors you need to consider though.  Miners suck down a lot of Electricity, so be happy knowing your power bill will go up a lot, or warn your parents if you live at home.  The second is Heat.  A typical miner throws a lot of heat.  if you live in a hot climate and don't have a decent air conditioner or place to put miners where it won't heat your house then I would say do cloud mining or don't bother,

9)  Not really sure what you are asking there.

Ouch, yeah that would suck as well.

As for the other question.  Cryptsy about 2 years ago was pretty much the largest altcoin exchange.  Not on the levels of the large BTC exchanges.  But it would be similar to what Bittrex or Poloniex is now.

Here this should answer it best.

Cryptsy went under about 1.5 years ago.  He claimed that the main wallet for the site was hacked, so he had to close down.  Others say he ran with the profits.  Either way, pretty sure I won't be seeing any of my missing coins again.  If you joined in the class action lawsuit, you might see something yet.

Cool, hope it succeeds.  I always wanted to mine coins all day, then throw them at Girls at night.  LMAO.    


Can't help it.  Best time to use a "Field of Dreams" Reference.

Build it and they will cum.   

I know the feeling.  I lost around 20 LTC, about 80,000 DOGE, and piles of other coins on Cryptsy.

Oh Well... Lesson learned about not saving things on an online exchange.  For me anyways.

Not really worth it to mine LTC with GPU, and not at all worth it to mine with CPU.  Don't even try.  If you really want to mine Scrypt coins via GPU, there are a number you can try that will pay out more, but still not enough to cover the Electricity.  Only way it makes sense is if you get electricity for free.


For that calculator, the Speed a decent GPU usually mines LTC (Scrypt) is around 1 Mh/s  more or less.  The power used is around 350W

There are a number of coins that you can mine with GPU like Sia Coin, Etherium ect.  Things with different hash types than Scrypt and SHA-256.  

For reference, I have 2 old Gridseed Scrypt ASIC Miners left over, that hash at about 800 kh/s, so a bit less than a decent GPU.  Mining alt Scrypt coins, I can pull in about $0.10 a day.  They nice thing is they only use 7 W, so they are still making money.  On a large coin like LTC, I would expect that to drop to around the $0.02 - $0.03 a day range.   Plus with the price of Electricity, I would expect that to be in the $0.75 range, so you would be losing money each day.

You really need to work on giving more detail.

You are a new member, and are saying you are going to create a coin that will revolutionize the Multi-Billion Dollar Adult Porn industry, but don't know if there is any interest in the Porn industry on the internet, and somehow your coin will be better than all the other Sex related coins in the past because yours will be used for the entire porn industry?? 

Don't have to go into detail that you are giving away trade secrets, but are you saying your coin will be used on all the Adult Porn sites across the internet?  Or that your coin will be used on the Porn Site that you want to create?  I can't see how your coin will be any different than any other Adult related coin on the market.  Look up Clitcoin's website.  Are you planning on creating the same type of website as this?   

Considering Adult content is the majority of content on the internet, I would say you would definitely have a market.  I did look up Clitcoin, after never hearing of it before, and their website does look interesting as a future project.  Maybe that is what you are talking about??   

Yeah that doesn't even make sense.  I'm sure everyone would notice right away if the hashrate of the Sia network didn't jump massively when they go online. 

If you watch when a new coin launches on an exchange, you will see buy orders as high as a few BTC, but with extremely low volumes to drive up the price, and then bids as low as a few satoshis.  No one really knows where they will land.  Usually if a coin has a large premine, or a large amount of coins, the price will be lower, but a lot of it has to do with speculation on if the project has enough interest to pull in buyers.  The entire price is based on what people want to pay for the coin, and not the actual market of the coin.

Good to hear you have a plan.  I would suggest taking things slowly.  Open your store first, then after maybe your second store you can look into an idea of making your own coin for your store, or maybe accepting one of the existing Cryptocurrencies instead.  You don't want to have to much on your plate at once. 

You also won't make a lot of money if you are planning a centralized coupon currency for your store that doesn't exist yet.  People do like to help someone with a plan, and a business plan, but you might be riding a bit early on that idea.  You will definitely get more traction once an actual store is implemented, and they can see what they are getting behind.

Trust me, I do want you to succeed.  I just don't want you to rush into anything. 

I have to ask.  How much money do you have into investing and creating a retail company?   Sorry, just have a feeling you don't already own a store, or have the funds for what you are describing.

Also, you have the idea of Decentralized wrong.  Decentralized means you don't have control over the coin.  And it's not backed by a retail chain.   It's created, then sent into the world, backed by people mining, and they are the ones to get the coins, not the company.  You may have a pre-mine to distribute, but the larger it is the less of a chance people will buy into it.  What you are talking about sounds like the exact meaning of a Centralized coin. 

Yep that is mostly correct.  The price/value of an alt coin has absolutely 0 to do with Market Cap, or anything of that nature.  The only thing Market Cap measures is a time slice on an exchange they are checking multiplied by the number of coins available.  It means absolutely nothing else. 

All exchange prices on ALL coins are based on Supply Vs Demand, and how much people want to pay or sell their coins for.  Nothing else. 

Add to that, Small exchanges don't automatically align themselves with bigger markets to avoid arbitrage.  The Market itself usually takes care of that WITH arbitrage.  Even in the large BTC market, the differences of prices on different exchanges can be HUGE.

Yes there is room for another coin to make 1000% in a year.  Alot of them actually.  On the other hand, there are even more that will worth 0 in a year.  If you watch, some coins can fluctuate 200% in a day.  (Mostly pump and dumps)

My advice, don't come in because you heard news of people making 100% on investment in a year.  Come in smart.  Read about the coins, and what the devs plans are.  And start day trading.  You will usually make alot more day trading coins than you will buying a coin and checking back on it in a year.  But at same time, day trading can lose you alot as well.  Don't invest what you can't afford to lose.

PS:  Your 100% increase is technically correct.  But don't forget, you will also have Commission Fees on top of that, and fees to transfer the coins from Fiat to usually BTC/LTC or ETH then a Commission fee to buy the coins you want to invest in, then more commission fees when going back to BTC ect to sell, and finally more fees to take the money out and convert it back to Fiat.  And until BTC fixes their fees to transfer BTC, in dealing with amounts in the $10 range, you will be down 30% before you even begin.

There are plenty of Adult based Alt-coins already.   If you have an actual project, you may want to talk to one of the Dev's, as they may do what they can to help you out, since they haven't really hit the market very hard yet.  One in particular would be Sexcoin.  I think they might have a few Toy shops, a few Cam Girls, and a few Escorts accepting it, but other than that, they need a good market.  

Aside from that, any other alt coin or even BTC would be happily accepted for any Adult project you have.  I'm sure whatever project you have is not on the level of what is on TOR, and they all happily accept BTC.


Edit:

Oh wait, are you asking if a Crypto coin would accept being in an adult service industry, or are you asking if you think we think that the adult service industry could use a Token based cryptocurrency, and that you would try to create it.  If that is the case, it's been done before, and hasn't have much traction yet.

Since each exchange has it's own prices for each altcoin, one could only assume that the prices "data" would be from sales volume and prices from that exchange only. 

Unlike most other coins, Sia is built around having a Cloud Storage backbone running off it's Blockchain.  You can "rent" out your HDD space for a contracted amount of time, in which you would receive encrypted files that could only be accessed by its owner, or those the owner shares it with via the Blockchain.  They are trying to compete with One Drive, Google Drive, iCloud ect. 

They need to have a lot of trust built up to have people entrust their files to be stored on their "cloud", and by creating ASIC's for their coin, they are taking a step towards trying to build up that trust.  At the expense of ticking off some GPU miners. 

Having a 51% attack and a double spend is bad enough for a coins future.  If they lost access to peoples files, or worse, made their files available to others, it would destroy any hope they would have of coming back from that.

I can say as a Bittrex user, they do break out the price into USD for you, even though you are using BTC to trade for the Sia coins.  For those that want to see how much coin prices really are.   

While possibly good for planet, I can't really see any reason to have tokens linked to a single farm.  Maybe Farmcoin??  Lol.  Please don't make that. 

Why not just use an already known coin like BTC, LTC or Etherium and use it to purchase shares in the company.  You could probably even set up a site much like a Cloud mining site, where the shares they purchase have payouts every day or so.

My biggest problems still would be the "with 0", meaning you are wanting people to invest in a company you want to create, and you are a totally new person here with only 8 posts.  With all the scams around here, I don't think you will get much traction, but...  If you build it, who knows how many investors you will get.   Just don't go in expecting alot.
