I’ve not transacted on Bitcoin much at all and I’m nervous about getting hit by a gotcha with UTXOs when I decide to move the contents of a cold storage wallet.
I funded it originally with 2 transactions from Coinbase (KYCed but don’t care) and it has been sitting there ever since.
Recently there was the news about a big player messing up their UTXO and accidentally giving half a million worth of BTC to a miner (who later refunded it).
Question is how does a novice avoid something like this happening when even the big players can get stung by it? Do most wallet apps handle all this for you? And what is the best strategy for the cold wallet. I might want to empty it in a single transaction to a new wallet or back to an exchange, or just move part of it. I want to avoid this mistake and avoid being left with unusable dust.
Thanks 🙏
