I am looking for the best wallet to safely store my bitcoin for the next lot of years (who knows how long) is bitcoin core a safe place to do this or should i look at others?
Bitcoin core is safe compared on web wallets because you have the private keys and you would able to retrieve it back when theres unexpected circumtances might happen in your bitcoin. If you are making secure on your bitcoin better to keep on cold storage paper wallets or trezor and other hardware.
Some online wallets actually let you create copy of your private keys, export it, store and import later to software wallet of your choice - for example Blockchain.info has this feature.
Bitcoin Core is the first and the longest developed bitcoin wallet. It is open sourced and it is probably the most trusted bitcoin wallet available.
If you want to learn more about it, I recommend this article:

Im not aware about that feature on blockchain.info where you can copy on your private keys that sounds really a good thing for me because i do use also that web wallet for fast online transactions . Thanks for this new information brother, i would try these feature and securing my bitcoin even on webwallets. I use bitcoin core too and you should really be careful on downloading malware on your pc and might get those bitcoins that are being stored .
