1. Transaction consolidation, this process is as simple as the name says it, you are sending all your bitcoins all at once to one address so that you already pay for all the individual data input for all your previous chonks of transactions. You can do that by waiting for fees to come down or you can try this second option
2. Liquid, liquid is a Bitcoin sidechain(cheaper) you can use to store those small individual chonks of transactions staight from your exchange for a lower fee. You can use something called "sideswap" on the sideswap.io app to automatically receive and swap your BTC to L-BTC for about 0.1% conversion fee, ofcourse you may want to first calculate if this better to use this service that requires some trust instead of using the Bitcoin timechain, it's a tradeoff you are making, but can also send L-BTC to a more trusted bitcoin wallet like Green. Now when you feel like your liquid stack is big enough and you want to peg-out to base L1 BTC you can simply sideswap it out on the sideswap app. You can also move those liquide bitcoin faster and cheaper using the following technology as well.
3. The Boltz exchance(boltz.exchange), this exchange will help you move your bitcoin from liquid to your lightning wallet visversa and from lightning to base layer BTC
