Stacking during pumps

1. I can't use ledger anymore if anyone knows the best self custodial wallet let me know please
2. Getting closer to 10,000,000 SATS.
3. Why does bitcoin pump a few days before I get paid lol my luck
4. Just keep stacking is the rule
5. I'm looking to get a lightning node and I've seen some people have very small portable ones, would love more info

Thank you
