I have an old wallet that had a bunch of dust transactions from early mining, plus a bunch of small transactions (mostly 0.5 XMR) from later mining, plus some big transactions from exchange payouts. Now, I decided to move it all to a new wallet, to consolidate the dust and small transactions, and also have the mnemonic seed. I couldn't send it all as one transaction, and had to break it up into about ten different transactions. No problem.
However, at the end, I have about 3.5 XMR that wouldn't send at all as the transaction fee(s) would be too large. I think this is the dust. Now I know 3.5 XMR is not a lot, but will dust be forever useless/unavailable? Is this a fungibility problem? It seems these 3.5 XMR are not as good as (interchangeable with) another 3.5 XMR.
Is there any way to consolidate Monero dust into Monero nuggets?
Cheers, Q
Yes, that is the dust from pools problem, which was fixed long time ago. You have two options:
1) send them with mixing of 0 in smaller chunks to another wallet of yours. Use the biggest it lets you - 0.5 or 0.2 XMR or whatever.
2) wait monero to go to the moon and then the fees for 1) should be much smaller.
*note that if you wait and cleaning old dust change happen (GingerAle:"maybe perhaps cleans up old dust.") you'll probably lose all the dust.
