The trust no one on this forum is a bit exaggerated. Yes, you shouldn't trust all the people with neutral trust but there are a few very trusted people with high trust. Their account will not be likely to be bought. If in doubt, you can always use an escrow.

Yes. For people who invested a lot of money into mining, they don't have any chances of getting ROI. If the new algorithm can be CPU mined effectively, botnet mining would resurface. Botnet mining are most probably stopped now since the difficulty is so high.

USB miners have no cooling, therefore you can't put efficient ASIC chips there. Also, after so much more efficient ASICs came out, the difficulty skyrocketed and they are unprofitable. These are only for collectors and people who want to mine as a hobby but do not want a big and expensive ASIC which emits a lot of heat.

Wrong concept. Even though those coins are ASIC proof, why can't people use their GPUs from mining BTC a few years ago to mine that alt coin? The difficulty would probably rise. You cannot predict if the price is going to crash. Those people with GPUs from mining Bitcoins year ago profit more than small miners.

Many people only wants to contribute to the network. They only take about a few dollars per month, many people just do it as their hobby. It is nice to see the lights blinking when they find a share.

I don't think it would be profitable for you even at 10% off. Also, are you going to pay 0.0001 fees for a 0.0005 transaction? It doesn't seem logical.
You are wasting a lot for something that gives you satoshis for 0.0005.

They host hardware for you and they either pay them for hosting or payout is deducted for electrical cost and maintainence costs. They are usually very over priced and they take high fees from your payout too. It is really hard to ROI.

It depends on how reliable are them, how fast they respond to your support ticket, features and security. In order for an exchange to be successful, they must be able to offer all of the above. They can easily beat old exchanges in terms of volume if you offer things better than them.

I don't think this GPU can be compared integrated graphics. Using integrated graphics cannot run most of the games and needs to be at the lowest settings. I believe that GPU and integrated graphics is at the same level of performance.

They support any kind of signature. The only difference is price. You have to custom specify your price per post as the default is PD's rate. They most likely wouldn't care what signature are you using.

Posting after the new period starts would give you 14 extra activity point. Using one would leave you with 13 which you can either accumulate or post a lot of post and your activity would go up. I believe what he is trying to say is that he needs to post once per two weeks to accumulate 13 extra activity points.

A new algorithm may be incompatible for ASICs. It isn't easy for developers to just make a fork and make all the users and miners to switch to a new client. It doesn't benefit those with big ASIC farms since all their hardware would be wasted.

There is still an enrollment list. It is rarely updated however. It is useful for members to check if they are enrolled and not wasting their time here. Errors cannot be prevented so many people still need Stunna to confirm it.

probably even longer if they even ship. The difficulty increase is one of the factors to your ROI, so is electrical cost. Unless you have electrical cost, it isn't profitable. The hardware might be faulty and you would have to send it back for servicing. Therefore, it is really really risky.

They have bitcoin value if there are loaded BTC inside. To redeem those BTC, the user can just tear off the hologram and redeem it. Physical Bitcoin are usually just for display purposes, Newspaper and magazine can't represent BTC well without physical things and pictures. Redeemed Physical Bitcoin can be resold again, for collectors usually.

I'm not sure if its true but some people said that if you have changed your signature to full member, you would be paid as full member rate. Stunna only calculates your payout from rank and posts. He doesn't know when you are upgraded and I don't think he wants to know when you are upgraded as long as you submit the correct number of posts and use the correct signature.

Coinbase is a shared wallet service which does not allow you to access your bitcoin directly as you do not have the private key. It is a hassle if they experience downtime when you need access to the coin. Blockchain.info on the otherhand, allows you to control your private key yourself by sending you a copy of it. You do not need to be afraid of downtimes since the private key will always be in your control. Blockchain.info is generally very safe with 2 factor authentication. Anyone can bruteforce your coinbase account with your email but not Blockchain.info since they need a long string of letters and numbers to access your account.

You can mine with a phone. However, note that phones do not have even a fan cooling. They overheat very very easily. The speed is smaller than a desktop CPU with even better cooling. There is a very high chance your phone would die very soon without cooling. The best is to buy ASICs or custom build PC for it.

Change the signature and do nothing. You don't have to re-enroll. During enrollment, you do not specify your rank.

0% downtime is nearly impossible. Even google can be down for sometime a few time a year. Pools which have 99%++ uptime is recommended. If the pool is down, you could always switch to a backup pool.
