I only learned about the advantages of using multiple wallets a couple of weeks ago. I learned that I have to have separate wallets for sending, receiving, and bills payments. That way, I could lessen the risk of theft and I could put my BTC in several wallets to spread out my eggs in several baskets, so to speak.
yes that is a fact and most of the people are using different wallets for security bases and people have good amount of money so they do not like to take risk and therefore they put their bitcoin in different wallet so that their whole assets should not be hacked in one time.
