I am looking forward to having a ledger soon anyway with all the hypes. By the way, if you are looking for a long time storage and looking to have lots of bitcoin, I will advise a cold storage as most people already adviced here. Hardware or paper wallets are good for that. Desktop wallets aren't bad too though but remember that those desktop wallets (most especially the light ones) are as safe as the PC you are installing them on. So be careful of malwares and don't just expose them if you are planning on sticking to one.
very good point. but the issue here is
offline wallets, which i take to mean cold storage. you shouldn't be setting up cold storage on a computer connected to the internet!
i definitely made some mistakes early on with altcoin wallets and malware years ago. when it comes to cold storage, i only use an offline/air-gapped machine that has no other purpose than to generate seeds and install/export cold wallets. BTC is just too precious to deal with any other way!
