I guess you are being funny here, I think you should have known this better by now. You have been around the forum quite some time now and you may have come across those post talking about buying of Bitcoin  and all that, including the right wallet to store Bitcoin perhaps you just want attention that's what I can only say. The answer you requested has been given to you even though you already know them and his in pretence. But if you insist I can only tell you to buy Bitcoin from any of the exchange like bitget or bybit and send to your non custodial wallet like trust wallet, electrum wallet, meta mask etc. where it can kept for a long time. And make sure you seed is intact with you because there is a slogan that says not your key not your coin.
