Back in 2014, when Dash was called DarkCoin, i've swapped out my mining wallet to a new wallet.
The coins all arrived, but never got confirmed. At the time, i didn't look back on it, as it was pretty worthless.

Today, it would be worth about 5.5 Million USD.

Enjoy my #cryptoblunder

This is worth an NFT
