In version 7.2 is nothing where I can update to 8.1 ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)
|
|

Can I also download on my other laptop version 8.1 and connect to my other wallet? I mean I have my address and the password...

stop your current mist wallet.
current mist version is 8.1 (i believe). update, when you fire it up it askes which chain.. new forked or old one. pick one.
then let it update the blockchain and see if it shows.
I just noticed that my wallet is version 0.7.2. Do I first need to do the update to 8.0 before I do the update to 8.1? Thanks so much! Im not a techie ![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif)

Folks,
I have downloaded an Ethereum wallet some months ago and deposited some Ether. Now after the hard fork happened...do I have to do anything? Ive sent 10 Ether to my poloniex wallet but it is still 0 of 12 confirmations. Do I have to download all outstanding blocks before the transaction is getting through? I have more than 220,000 blocks outstanding.
Thanks to everyone!

Folks, Im very excited and waiting for it since 2,5 years. I have bought a lot when it was around 200-300 and I dont care if it crashes to 400 or even 200 again. Im a longterm holder and see as an investment for the next 10-20 years or even as part of my retirement. The fundamentals look great in Bitcoin and its growing steadily. This is what is for me the most important point. Im a trader and in my opinion there is nothing currently where you can put your money in. Im very positive for the future. Happy halvening to all ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Hi folks,
Im wondering why we have such a big spread between the GBTC (Volume exploded in the last weeks) and all other BTC exchanges?
Currently GBTC is trading around 1,300 USD All other exchanges around 700 USD
Why do we have here such a big spread?
Thanks in advance

Folks,
why is it such a big deal that CME Group is going to set-up a Bitcoin Index? Maybe Ive understood something mit carefully but the NYSE has a Bitcoin Index.
Thanks for sharing your opinion

Ok, but how good are the companies like Skry and Coinanalyticsto to track bitcoins? Any ideas?

Folks,
do you know of any EU Regulation regarding AML on Bitcoin? I guess it is still in his very infancy.
Thanks

Folks,
Im wondering on what always the longest chain is based on. Is it on how many blocks or on how many transactions have been included.
Most people will tell you that it is based on how many blocks are in the chain. As a general rule of thumb that's a reasonable explanation, but technically it isn't correct. The "longest chain" rule is actually based on the total proof of work. Usually blocks generated at the same block height all have the same difficulty target, so more blocks means more proof of work. However, if someone were to go back to the genesis block and try to generate several hundred thousand blocks at a MUCH easier difficulty target than the existing blockchain, their chain would still be "shorter" even if it had more blocks because it would have less total difficulty. For Example - lets say you have two chains competing:
1st chain has 6 blocks and every block has 100 Transactions (total 600 transactions)
2nd chain has 4 blocks and every block has 400 transactions (total 1600 transactions)
Which is now the longest chain and on which are miner now looking on?
Assuming that they all the blocks were generated at the same difficulty target, the 1st chain is the one that miners would choose to work on. Choosing the 2nd chain would result in all other miners rejecting your block, and therefore you would waste your effort (and money) trying to build on it. Thanks ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) How is it if two blocks are being published at the same time. One block with 100 transactions and the other block with 200 transactions included. Is the latter one taken or are miner not looking on the transactions included in the block? The intention is for miners to use the first block they receive. So some miners would receive the 100 transaction block first and would build on top of that. Other miners would receive the 200 transaction block and build on top of that. Eventually, a miner would solve a block and broadcast it. This would make the chain they were working on now the "longest". All miners that were working on the other chain would abandon it and switch to this new longest chain. The block that didn't get built on top of would be considered "orphaned". Wow, thanks for the long explanation!!! I got it!!! ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

I mean if companies like Elliptic and Skry are successful Bitcoin will be not anymore that annonomyous I guess...
|
|
|
I undestand but how about the companies like Elliptic and Skry (former Coinalytics) which are trying to trace bitcoins in the blockchain?
|
|
|
But if someone really wants to launder Money over bitcoin, he could buy bitcoins over localbitcoins or any other black market? Send the bitcoins over 100,000 addresses and nobody can trace it...is that right?
