How many words are in the word list for multibit seed generation?
and could anyone tell me what is the entropy for a 12/18/24 seed length

I personally like backing up my whole Multibit folder offline by using a USB drive. The data folder is located somewhere in the application data folder in Windows and in your home folder in Linux. Note that the app data folder might be hidden in Windows so just unhide hidden folders for it to be easier to access.
If you want to be safe, it would be better to cut that folder out of your computer and place it in a couple of USB's. You can also encrypt that folder by using open source encryption software that can be found online. I hope that helps.
But i was reading that after you spend anything the client makes new (change) address automatically so if i have the first private key the one that holds BTC now and use it will that money be still on that private key or after spending some little amount i have to make again fresh backup? |

So if I understand correctly it doesnt make a request with only the address that is personally being used but it downloads the entire last block(?) and it check if the transaction is found? No. It tells the peer to set a specific bloom filter. That filter means that if any part of a transaction (hash, outputs, inputs, etc) matches that filter (i.e. do some operations with the filter and if it matches one thing should return and if not, a different one). If there is a match, it will relay that transaction to multibit, otherwise it will not. Multibit then has to check the transaction itself to see if it pertains to the wallet. Bloom filters have the effect of having false positives but no false negatives. That means that every transaction that the peer relays to Multibit may not actually pertain to the wallet, but the wallet will receive every transaction that pertains to it. So does it offer any privacy at all? The guy running multibit node for getting balances of address is he able to see what IP address looked up which address or no? |

if i backup the wallet file(private keys) is such backup enough? i plan to restore it only like once a month from usb to maybe to check balance and maybe sometimes make a few transactions

Can anyone give me easy explaination how bloom filters work?

From what I understand in this case it wont matter that the user IP is exposed since when multibit will try to get balance of your address it will in the sametime try to get balance of other addresses that dont belong to you is my understanding of bloom filters good? and are they enabled by default

Is my understading of bloom filters above correct?
If it's not can you please explain how they protect anything

So I got 2 conflicting answers...so des the someone running electrum server can see my BTC address tied to my IP or not? If yes,is it the same with Multibit?
The person running the Electrum server can see all the addresses tied to your wallet. It is not the same with Multibit because multibit does not use the same structure. Multibit is pure P2P so it relies on actual full nodes. It uses bloom filters to provide some privacy. What about the IP addresses (I believe that's what OP asked)? I've read quite a few about it and all of them seem to indicate that the servers can indeed see your IP address, are they all wrong? From what I understand in this case it wont matter that the user IP is exposed since when multibit will try to get balance of your address it will in the sametime try to get balance of other addresses that dont belong to you |

Thank you for the answer but are the new version of multibit secure?
Yes. I don't recommend Multibit because it makes it harder to do advanced tasks like import/export private keys, signing raw transactions, etc. However, if you don't need any of that, then Multibit is fine. I am just trying out Multibit and it seems to be much better than electrum at first look,no idea why more people recommend electrum But i created a test wallet and it gives timestamp and then on verification step it ask to put timestamp or leave blank if unknown but if i leave blank i cant press next and if i put a fake timestamp it also cant press next so have to give real timestamp,and cant use without the timestamp? |

When using Electrum I think for it to update balances it must make some request to a server with information about balance on specific address so it means that the person operating that server can see that a specific BTC address belong to a specific IP is this true? and if it is how to avoid it

Just tried Electrum and i can only make english so where are the others
|
|
|

But in electrum there are 2048 words that are public so we can consider that each word is 1 alphabet letter so brute forcing a 12 character password from 2048 pool doesn't seem that hard to do? And after the seed is used is it possible to force it to use user generated password for make any transaction or after someone gets seed they have full access |
|

The electrum seed is 12 words randomly generated from 2048 words list
the word list is public and everyone know what the words are so for someone to brute force it they dont need to brute force 12 words but simply 12 characters since every word is known
how can it be secure?
i want to store some of my BTC with electrum but i just do not see how a 12 word seed from 2048 public words can be secure it seems like very bad protection
