Theres also nothing stopping you from making an electrum wallet with utxos from dozens of different wallets without actually consolidating them.

Wouldnt highest cost basis be more recent thus possibly forcing short term capital gains?
I consolidated a bunch of purchases into a single wallet this year, no sales however. I don’t understand what I need to do? No sales, no gains, no? No shitcoins just btc.
You have to decide now what method is best for you 60 years from now or some shit. Some view this as a gift 😆
