I just divided it into several parts and not all the coins I hold I save in one wallet. I save it in several wallets and some trusted exchanges, even though saving on an exchange is risky, I just believe all who are in the online world have their own risks. So as long as we can find a wallet and exchange that is truly trusted, so far I still feel comfortable and don't get serious problems.
Yes, we have to divide the coin which is held to several wallets and exchange. Because with this, we can protect the assets we have. Because now a lot of wallets are hacked as well as account exchanges that are scam. This can avoid big losses, just imagine when we store in one wallet and we lose access to the wallet, of course it will make a huge loss.
