1. You must split your coins in 2-3 wallets, to avoid losing all your coins if they are all in one wallet. But then you don't know what types of wallets to use.
This method really needs effort and if you can do it then it is good as other said that don't put your eggs in one basket which is true that is why putting it to other wallet or if you can diverse this then it is good. I know that this is best method but i am not practicing it meaning i just very cautious in a very steps. Hacker can easily hack you but if you are aware you can prevent it
