point it i NEVER had to do anything to keep my corn. addresses i made in 2011 still work. the coin is still there. and i will never need to move those coins to some new format or lose them (well maybe when quantum computer are common).
altcoins swapping to tokens, = you really need to keep updated on them every 2 weeks at most, or at least every month. The ones I still have, somehow I managed to keep up with multiple swaps and still worth at least $100 ~ $500 for me, so I just let them sit and watch if anything develops. The developers and community seem sincere enough and continue to work on them, they simply are just not BTC, and ... you know the rest of the story.
As for your ancient 2011 legacy bitcoins, I would suggest you do try to move them to new addresses now, wait until the fee is reasonable or low *, or if you do need to move them anyway, make sure the change address is to a new format, the ones that start with bc1qxxxx so you save on future fees.
Then you might want to check if you have any of the fork coins too after that. If you had unmoved coins from 2011, you should have all of the other forks up to today, at least try to get some value out of the bigger ones BCH, BSV, BTG, BTD? (diamond?) not sure about the last one. They will at the very least pay for the transaction fees of your king daddy coin.
* sites I use to check current fees:
https://bitcoinfees.net/https://mempool.observer/https://jochen-hoenicke.de/queue/#BTC%20(default%20mempool),2h,weightThe last one seems to be the most "accurate", I simply set it to 2 hours, default, and weight, then mouse over the end of the chart and look at the number near 1 vMB, which is around 40+ to 50+ sats right now. Then I double and triple check using the other two sites to see what they say (check to see if they also updated recently, maybe refresh the page, you will notice if their last block is like more than 600 minutes ago or something.)
Since you haven't moved any coins since 2011, you can probably get away with a low fee and just wait a day or two and it might confirm. But calculate the total fee value for yourself, and the difference between $1 and $5 or even $10 might not be worth the time waiting for a confirmation block.
If you have one whole coin or more, worth $58k-ish as of this post, then spending $20 to move it to another cold storage native segwit address (and grabbing the fork coins in the process) could be worth it.
