I want to take my BTC investment to another level,so which of this wallet's listed bellow we serve me for a life time,that even my wife or children can access,if it goes other wice.
Software wallet
Hardware wallet
Centralize exchange wallet
Paper wallet
Your post is not quite clear but I believe you are asking which is the best wallet for bitcoin storage in long term. I recommend purchasing a hardware wallet. Exchanges are not wallets. Using a centralized exchange to store your bitcoins is a big mistake because then you don’t have access to your keys which means you don’t have true ownership of your bitcoins.
Recent events should make everyone withdraw all their coins to their own wallets
