I don't think that any coin will replace bitcoin...it is more a matter of which coin can work best alongside bitcoin.  Up until this point, it looks like it will be litecoin because of the faster transaction times, and the adoption slowly getting picked up by merchants.   It is seemingly like 2 years on bitcoin's tail...

its not only Kazakhstans its also some other countries also calling thisn Ponzi even in European countries

Which one? I see only competitor which copy the idea and put it in a new gift wrap paper, give a new name and change some terms, but below the line there are only Bitcoin clones.

The only one which are complete different are the pre mined one like ripple e.g., but exactly the difference make ripple not attractive for the Bitcoin comunity, who lost the trust in centralized and controlled currency.

You don't, you use a wallet

Bitpay is safe but idk about that site
Lol you're heads on wrong

Encryption had been around for a long time before the first papers on the idea of making a cryptocurrency were written back in the late '90s. Then, it was more time before the "theory" was developed enough so that someone could actually develop the software. Then the software had to be developed.

Even with manufacturers adding hardware to all the new motherboards so that the NSA can spy on everyone right at their source, their home computer, people will still figure ways around this. For example, there are methods, right now, for printing graphene microchips on plastic film. With the advent of the 3D printer, we will all be making our own computers, right at home, in a few short years from now.

Anonymity is not necessarily being hidden. It might be something like the Matrix movies - hidden because of similarities to everyone else in the crowd. There just might come a time when there is enough garbage info broadcasted out there that even a quantum computer will not be able to sift through it all. That is anonymity.

Because it would undermine confidence in BTC and it's not necessary at all. Just split them up!

Yes, thethingis, this is really no issue to worry about.

You should be glad about every BTC taken out of the game, because it gives your BTC a little bit more value.

Ok.  What are all the things I've bought with bitcoin? 

The reality of privacy is somewhere in between cash and credit cards, but I think its much closer to cash.  Also, please consider that today's cycle: exchange->purchase->exchange makes identification much easier since people are identified at the exchange.  But as Bitcoin becomes more popular and is sent person-2-person like cash it will become more like cash WRT privacy because it will be very hard to trace a chain of 20 transfers (you have to ask all 20 individuals who they sent it to) to find the 21st.

But of course if some address in the chain of transfers is also used to receive money from an exchange, then a short-cut exists.  So the difficulty to trace really is the shortest path from the transaction in question to an exchange.

You can have a petahash miiner right now
Just buy an old brewery or something and fill it with antminers or such
Now seriously, petahash is too much to fit in one device with the current chips.

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency.

http://www.pbmining.com  is one of the best posted on this forum, they pay out on schedule.   Downside :  they're down.  Some website functions are available but there is no buy in ... and it's starting to look bad for buy-ins at lower GH, as they are limited in supply.

https://bit-mining.co looks interestingish... I have only -just- seen them and have no experience with their service yet.

good sources dry up fast... scammers abound with all kinds of strategies.  DOGE is starting to look better ALL the time.

If the odds are good :  the goods are odd.
