The term "dust" has changed significantly over the years. 1 mbtc, which is 100,000 satoshis, used to be dust and many users thought it won't ever be worth moving that dust.
But I assume there is a shift going on in users' minds when they look at their wallets with leftover satoshis. The way these wallets are maintained or looked at has changed I suppose.
Am gonna spread this knowLedge out to some folks because this is very vital , most folks have the habits of abandoning their little assets in their wallet and they end up losing every access to that same wallet which may cause loss of funds .
The funny thing is that there are folks at that would have make it big in this bull season but because they assume their asset where dust then they up abandoning and losing their access to their wallet , because having a left over of 0.005 BTC when the price of BTC was around the range of $1000 it will worth $5 and some folks would assume it dust but now at the rate of $100k that would have left the folk with $500.
So no matter the how small the left over may have seen then we should keep the wallet seed phase safe because that leftover may worth something tangible as time goes.
