Most of the graphs have been running parallel to each other lately and a lot of these coins have risen too much.  I've noticed just a few coins that stand out from the crowd.  I think that these coins have not been crazily hyped as much as all these altcoin pumps recently (Viacoin looks like a "pump", but in perspective it's nothing and the coin is getting somewhere).

-GBYTE/Byteball - DAG based coin.  Very low transaction fees and they are static to create an intrinsic value (the value of transferring bytes of data).  Allows conditional payments e.g. when BTC received, send GBYTE.  A lot of good ideas there.  You can also get free bytes by participating in the airdrop, and the number of users naturally increases which causes the market cap to increase.

-AMP/Synereo - social networking coin.  Beta release tomorrow, so very early days for this coin and I think it's a decent opportunity.  There's a lot of good ideas here too, like storing personal information in an encrypted/decentralised way (imagine MaidSafe).  Not just a Steem rip off, and it'll be mental in the next week or so.

-VIA/Viacoin - interesting roadmap, super active development, SegWit implementation soon.

Disclaimer:  I am not responsible for your gains and losses, nor should this necessarily be treated as investment advice.  I just think these are very good coins set to rise in the near future.

1.  As I understand it, there's a block approximately every 10 minutes.  But when I pay a high fee on my transactions, I've had confirmations happen within 30 seconds or so, and the stories of people accidentally paying really high fees seem to result in instant confirmations.  How do they confirm before they're included in a block?

2.  Coinbase have fees several times higher than other exchanges (a static 1.5% to Bitstamp's 0.1-0.25%).  However, people still use them over Bitstamp.  I'm guessing that it has some relation to the fact that Coinbase has no spread and only one price, but I don't get it.  Can someone explain?

3.  Are public keys related to a whole wallet or just single addresses?  As I understand it, they're displayed with each transaction, so if it's related to a single address what would happen when a transaction is sent from several addresses, and if it's related to a whole wallet why wouldn't it reveal a person's association to other addresses that they own?

4.  I'm a bit confused about the trust system.  I read theymos' thread about it, but I still don't quite get exactly what causes someone to have a positive rating, what the multiple different numbers mean and how DT members tie into this.

5.  The transactions that I send are only to one address, but there also shows Bitcoin being sent to a second address.  What is this second transaction (it's not the same amount as my fees)?

6.  What are inputs and outputs to a transaction exactly?  At first I thought they were just addresses that you received Bitcoin in and addresses that you're sending to, but now I think there's more to it.

7.  How important really are full nodes?  People seem to talk about the node count, but can't SPV be good enough for the majority if there's just one honest node willing to relay your transaction?

8.  What are "anyone can spend" outputs (SegWit), and "witness blocks"? 

9.  In a hard fork, is there automatically a chain split or can a large economic majority render the old chain meaningless, and in a soft fork, does the chain split if a majority of hashrate moves away from the soft fork again?

I'm not a complete idiot, but I'm new so try not to add any more questions for me in your answers.  Less techy explanations please.

I'm pretty new to Bitcoin and the idea of cloud mining seems pretty appealing. However I keep hearing about Ponzi schemes which rely entirely on new members to stay alive.  Besides the blindingly obvious, what are the main signs that a service might be a Ponzi?

I've seen a lot of people arguing that Bitcoin can be profitable because of its volatility and convenience, but sometimes I feel that people using Bitcoin as an investment have little enthusiasm for its main use as a means of trading without an intermediary.

Under what circumstances should Bitcoin be treated as investment and to what extent should people think about its use as a global currency?

This is a bit late but you guys remember when Richard Spencer got punched in the face? I saw a lot of people on one side talking about not hitting someone for disagreeing with you and some people saying he deserved it for being a Nazi. So I was wondering, what do you think makes them a Nazi rather than just nasty?

I've been told by some articles that I should change my bitcoin address regularly, and some even suggest that I should change it after every purchase.  Can I have your advice on how to keep my addresses safe? Also, can anyone explain to me why I need to keep changing the address, since they can't send bitcoin without access to my wallet?
