I think it is not wise storing coins with 3rd party services, so I avoid them at all cost. Some scenarios like buying and selling coins on an exchange, would necessitate a scenario where you have to leave coins on their platform to execute a buy or sell order, so it is unavoidable.
I would rather split my storage into long-term and short-term storage and store large amount of coins in hardware wallets and paper wallets for the long-term and then having small amounts of coins stored on online wallets or exchanges for daily use.
How are you spreading your coins to reduce the risk of losing coins and still being able to use it daily?
This is an interesting topic earlier I used to store all my coins on coinbase, and then I came to know that exchanges get hacked very easily hence I stopped storing my coins on exchanges. Then I started storing my coins on Electrum wallet, and I have never looked back as it’s secured and super easy to use. I don’t use my coins daily but since I’m using Electrum I can buy or sell anytime I wish, if that’s what you’re asking.
