Been seeing a lot of whitepapers of new exchanges that claim they can aggregate order book from different exchanges to allow for best rate and coin options for investor. While the idea sounds great, I wonder how this will actually work?

Given most of all the exchanges are centralized, if a user from Exchange ABC would like to buy Bitcoin from Exchange XYZ, how can trade be handle seamlessly? Also, once trade is across different exchanges, how does one go about ensuring proper and valid completion of a trade?

Would love to hear any comments and thoughts

Just to confirm I understand this, basically, I the crypto seller will have my crypto escrow into an exchange wallet? An upon my confirmation that the paypal payment is legit (with no chargeback), I will press the confirm button to release the crypto from escrow?

Wonder how the situation will be handled if the payment is pass 90 days via paypal (a valid payment), yet I forget to release crypto from escrow? Does the exchange perform an automatic release after a certain number of days without confirmation?

Would like to hear about the most memorable ICO advertising you remember? Why? Did you ended up investing in the ICO due to the advertising or actually did the dd on whitepaper and the team?

Given all the preset block time, could some one kindly advise how crypto exchanges go about handling the instant transfer of crypto pair between buyers and sellers? Do the trades and the change in cryptos as a result of the trades just resides on database server within the centralize exchanges?

How does exchange go about handling withdraw from clients? Do they have hot wallet to keep a float to allow for instant withdrawal when requested? If that's the case, how can they ensure they don't over/underestimate the required float?

Would like to know where do the popular exchanges register as business. Not where they operate or where there office is based, but rather where the company is registered? I have heard a lot of exchanges are actually incorporated as offshore entity to minimize any legal ramifications when things go wrong.

Also, wonder what if any protection is there for crypto investor? I mean I understand you are suppose to store all crypto on cold wallet but it is inevitable to have crypto in your account on exchange as long as one wants to trade.

Wonder what is the cause of the dramatic cost differences between binance and poliniex?

Would like recommendation on best exchange to trade on and reason why you believe the exchange is better than others?

Lately, I have been seeing many crypto ATM that converts cash into crypto. I am having a tough time understanding the logic behind such machines. I mean, why wouldn't I just go to an exchange and buy crypto? I see no added benefit other than the rather high fees being charged.

Would like to know if any of you have used such an ATM? If so, why?

If you have never used such an ATM, under what circumstances would you consider using it?

The fact that this is not a giveaway aside. Can you provide more details on what does a master node do? Why is your master node something that one should purchase? White paper and any details relating to the coin you mentioned?

Would like to learn more about bulk order from AMD. Wonder how you go about arranging that? Through a connection? How many cards would be need for such an order?

New to mining and am seeing a lot of acronyms that I have absolutely no clue about. Would appreciate if someone can help explain what each mean and which alt coin the term will be applicable to:

Luck - I assume any pool have a chance in obtaining the next block regardless of hash rate? In the event that a pool is luckier than other, workers will get more than actual hash rate of the pool? Are historical luck any point of reference for future luck of the pool? Or is this just something completely random? IE: The luckiest pool can turn out to have a string of bad luck on subsequent blocks? Does this apply for mining of all coins?

Orphan rate - I heard is no payment for work done. But then again, I heard that some alt coin/ mining pools offer payment for orphan block. Wonder what alt coin/s this term is applicable to? 

Uncle rate - I heard  this means less payment for work done. Again, not sure which alt coin/s will this term be applicable to?  How much less would one be paid on uncle vs actual ?

Stale share rate - My understanding is that this refers to no payment for work done. Wonder when do such situation arise and if there is anything one can do to prevent stale share? 


Payout scheme - PPS, PPLNS, RBPPS - These I have absolutely no clue about.

Thanks everyone for being so kind and helpful. I have already learn heck of a lot from all the other replies.
