So it now costs US$8.42 to send US$21.28 from a Ledger Nano Wallet. This has got to be the mother of all rip-offs!
From a bitcoin balance of US$29.70, I was shocked to suffer loss amounting to one-third of that balance to transaction charges. To worsen matters, this ridiculous fee was charged for "slow confirmations" while the "fast confirmations" gobble up close to US$10.
Consequent to the afore-mentioned, I am now seriously considering early-retirement for my Ledger Nano.
