Hi

Do I need to save only my Electrum seed or will my values be more secure if I also store my private keys on paper?
For example, I want to make sure my funds are still available in 5 years from now. What if Electrum by then somehow doesn't exist anymore? Can I access my wallet and funds from another provider using my Electrum seed? Or would another provider only be able to create my wallet with my existing funds if I can provide my private keys?
