This is a newbie question for sure, not just the use of English but that which you are inquisitive about. There is really no point having your bitcoin split and saved on several addresses. I won't do that! You might feel secured that way but, if i may, any msiconception on any step of the way could make you loose a lot. Avoiding being scammed through wallet hacks or having it brute forced could be the idea behind such strategy but, its not the best. A 2FA would be a better way to go about extra security.
