Perhaps some of your difficulty in understanding what is going on is that you are ascribing "the US" and "China" as real entities capable of action or intent.  In fact they are labels that real individuals and actors capable of action use as shields for various purposes.  This is well discussed by e.g. Buckinminster Fuller's books describing "England". 

I wanted a topic to discuss the ongoing crash of 2016.  The other Economic Devastation topics have become too cluttered. 
 
The premise of this topic is that this is not a blip, and the crash happens this year.  Personally, I think this recent movement upward will be short lived and the real catastrophe will happen in March.  But perhaps I will be wrong.  Let's discuss how long it will take us to recover from the impending devestation, *if* we will recover, and what effect this will have on cryptocurrency.

by rate of electricity compare to foreign is btc mining will profitable here or not.and if profitable then how much compare to other while i could make firm on foreign.

I would start with raspberry pi, since you have more chance do hand on stuff.
Learning something is your goal, not actually make the return.

So recently (today) I was watching Deadpool. It's that cool ass movie that just came out. So at that cool little bar in the movie that Deadpool hangs out at there's something in the upper left corner that I barely noticed. It's a sign that says "Bitcoin accepted here". After seeing that, my jaw dropped. Bitcoin just made it into pop culture! It's pretty awesome seeing this in such a popular movie! Pretty awesome stuff.

there are so many important news from the member who replied to this thread..but i have a question,is there any chance to reach the btc price again $0.001 or $10,000 in the next 5 years?

Ethereum is a system of redundantly executed code, a general purpose CPU mirroring the functionality of the worlds most inefficient botnet without parallelization.  Unless blockchain scaling is either huge or infinite, the validation and redundancy of simple transactional data, which Bitcoin attempted to solve in a distributed manner, is far more useful in a cost benefit analysis rather than open ended computational redundancy.  In other words, Bitcoin is an ASIC for a specific purpose, and struggles to fulfill that role even with a streamlined design.  Ethereum, on the other hand, has introduced an objectively less efficient design to try and conquer even more problems.

Such a design would obviously be dead on arrival out of the gate barring any other factors being introduced.  This is where partitioning comes in.  A partitioned network allows load to be split in order to scale further.  Here comes the paradox.  If the entire purpose of Ethereum is a system of redundantly executed code, how does partitioning even fit in the picture in the first place?  I guess you can say, ok, we're arbitrarily defining how much redundancy is enough, but how do you actually determine that?

As you can see, Ethereum is effectively useless without partitioning because it relies on scalability far more than Bitcoin does, while Bitcoin is struggling to achieve any scalability itself.  When you see Mike Hearn talking about using Ethereum as an OTC derivatives settlement, that functionality will be non-existent without partitioning.  The load carrying capacity would be far too small and fees far too large to do at scale.  It will be a case of centralized services vastly outperforming decentralized ones.  Who cares if it's trustless if it costs 10,000 times more?

Transactions can be bundled in Bitcoin without much of a side effect in order to scale, while bundling computational redundancy in Ethereum would defeat the purpose of it existing at all.  This is in addition to the fact that nobody has successfully deployed a partitioned cryptocurrency in the first place.  Fuserleer has been working on one for years and has been unable to release something.  IOTA is about to release.  I haven't dug through it enough myself, but Anonymint claims it's doomed because it will rely on centralization for convergence.

In summary, through bundling or even just plain on-chain transactions alone, Bitcoin can just barely reach functionality of an internationally used currency, at least justifying it's market cap.  Ethereum operating as a "world computer" is an obvious stretch of the imagination.  Since they issued an IPO money grab for their coin supply, I think most investors will already be considering the coin a failure if it has to dilute investors to infinity by leaking mined coins forever.  No actual secure PoS network has even been invented so far, so the coin needs not only one, but two cryptocurrency firsts in order to be considered viable - a valid PoS network and a partitioned network.  In order to even think about touching Ethereum, you're basically required to ask yourself, is Vitalik an order of magnitude smarter than Satoshi?

no, it's not possible anymore, unless you spam the board with multiple account, i guess in that case it's doable, but highly susceptible to a ban, form both mod and manager of the campaign

You need to ask for a refund. They were wrong.

There are no limits for capital gains reporting in the US. Every $1 gain should be reported.

The $600 common misconception is the limit at which a business needs to issue a 1099 form. Nothing to do with gains.
