What about Android?
Most of people who got scammed lost their BTC on shady exchanges, how's OS relevant in this case?
after I use Windows, I have been robbed and now I switched to Android, whether the risk will be higher?
Why not buy a hardware wallet ?
where can I get it? I do not know about the hardware wallet
Hardware wallets like Trezor are effective in stopping malware since there are currently no designed for it and they have anti keylogger features. IMO it is a good investment for huge amount of BTC. For small amounts go for paper wallets generated on offline computer.
ohh yeah I've heard it, even once there is one of the web when first launching Trezor giveaway.
quite expensive? like its hard to get it in my country
I would say its expensive for someone storing a tiny Bit of bitcoin but a wise investment of someone storing a hundred or thousand of Bitcoin. Its worth noting that it is not waterproof, though water resistant. It may cause damage to your device since it isn't 100% waterproof. Water will eventually go inside due to high water pressure if submerged for a long time.
yes it is very suitable for large investors, which saves 100btc up.
if like me just looking for free and do not necessarily BTC monthly income, no need to buy it
