I have about .03 of BTC in dust. It's from a cloud miner.

Sadly, not thinking it is all in an HD account that I set up, with a different derivation path than my primary BTC. I wanted to keep it separate so I could keep track of how much was mind.  This means those small output's can't be combined with larger ones when other spends are done, to keep the size down. If I try to send it all to another address, I am told the fees would cost more than I'm sending by coinomi with a .002/kilobyte fee set. I even dropped the fee down to .0014 per 21.co's web site.

So, is there anything I can do to recover/use any amount of this stuff.

I think this is one of the big flaws of Bitcoin also. Is anything being done to address this issue... it really makes bitcoin very bad for micro payments.


 

I think I've gotten to the point where I have enough bitcoin that I don't want to keep it all in mycelium anymore.

So, paper wallet created on air gapped computer seems to be the most secure. But it has downsides like hard to spend if needed, could be lost, could get destroyed (sure keep several copies).

Coinbase Vault means I have to trust coinbase since they keep the keys. Unless I use the "I keep keys" version and then it seems the same as BitGo to me. however, seems most convenient, I just need username/password/2FA device.

BitGo sounds great but I still have to trust them a bit right. Also, are they still secure? Didn't bitfinex supposedly use them and still go hacked, or what that because bitfinex just didn't keep their keys/password secure enough?

I guess there's also Trezor, but that cost money and I guess could become damaged.

Thoughts, recommendations?

I have few question about blockchain.info's My Wallet. (Yes I've read the help).

First, on the privacy page it states that if you want Alerts/Notifications you "expose" your Public Key to Blockchain.info. What are the ramifications of this? Does that identify me in some way on the block chain? Does someone getting my public key mean they can look at all my transactions at every address?

Second, double encryption...

I am assuming with a single password, that password is the key use for the wallet encryption as well as the credentials needed to be able to d/l said encrypted wallet so that the Javascript is able to get access to my private key to sign transactions/messages.

When I add a second password, does this mean the encrypted wallet is encrypted again before it is stored at block chain info. Or, does this mean rather than the wallet being encrypted with the main password it is now encrypted with the secondary password and the main password is only used as a credential to be able to access the encrypted wallet?

wrt 2FA. Is this only use for logging into the web site. Or is it also used to spend coins? Rather than a second password, I would rather have to enter the 2FA code before sending. ALthough, I assume that would only work with BlockChain, and if my wallet (private key) was compromised someone could import it into another client and spend my coins without needing the 2FA code at all.

Finally Escrow. There is a second in the Help about Escrow but it doesn't go to a help topic. Does Blockchain.info have an escrow feature?
