Old-Dutch Get a hard wallet. Take all your coins off the websites / brokerages etc. and put them in your hard wallet. You can do what you like with them then. Get a physical password safe too.
Warning though, if you buy some proper esoteric coin where you have to sacrifice your first born to some ancient Sumerian fertility god whilst standing on one foot in a a bucket of custard and listening to Trisco - Muzak, you might find the wallet won’t except it, yet. The wallets get updated regularly with new apps as different coins get more popular.
