cloud you give me the reasons, why will never close our account? besides XAPO right now I also use coinbase, is this also good and safe to save my bitcoin? and how much for transaction fee?
Blocktrail wallet, unlike some web wallets does not control the private keys for its users. It means that they have no control over its user's keys and they cannot freeze anything. Even if they close down, the user can easily recover the Bitcoins via a backup. This also means that the transaction fees are fully paid by the user, deducted from their balance.
From where we can know if we have private keys in blocktraill wallet?
I want to know, how do we can refunds if they close (through the site address)?
Why, if no transaction received but my wallet address always change?
Blocktrail provides HD wallets for your safety and privacy. You can create an unlimited number of addresses to help protect your privacy
without the need for multiple private key backups. Our system will also generate new addresses for change and fund requests automatically.
When you sign up to Blocktrail, we give you a backup PDF (which you should definitely store safely) is your "complete ownership" to your underlying coins, with the backup PDF you can always recover your bitcoins when necessary, even when Blocktrail would be offline.
You can do this with our recovery tool (
https://recovery.blocktrail.com/ source:
https://github.com/blocktrail/wallet-recovery-tool), read more about it here:
https://blog.blocktrail.com/2015/11/blocktrail-wallet-recovery-tool/The recovery can also easily be ran locally.
The reason why exporting private keys doesn't make sense anymore with most modern wallets is because they are HD (hierarchical deterministic), the fact that exporting private keys is such a horrible backup solution is actually the whole reason why HD wallets were invented.
You now have 1 future-proof backup that doesn't need when you create new addresses (which for privacy reasons you should be doing for every transaction).
Another reason is that the Blocktrail wallet is a multi-signature HD wallet, so recovering your bitcoins using a different wallet isn't as simple as just importing private keys, the wallet which would import the privatekeys would need to have some extra code to understand how the multisig HD is structured and the same for other multisig HD wallets (because they're all slightly different).
Hope this answers your questions, let me know if you have any more.
Thanks
