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?
i think bitcoin core is the official desktop wallet for bitcoin. You can see the link to the bitcoin core is posted in this bitcointalk.
the most important thing is you must protect your wallet, and you should never expose your seed or key to another website.
Backup your wallet info and store it in different safe places.
