I've asked many people, big and small, which wallet bitcoins are the safest to store long-term.
Many of them said to keep Bitcoin in Binance Account, Ku Coin Account, Trust Wallet.Now my question is if I keep my bitcoins in these wallets will I be able to use them whenever I want and will it be safe.
Are there other wallets where bitcoins are most secure?
I want your opinion.
Who are those many that have said to you that keeping on exchanges account are a safe method for storing your Bitcoins there for a long time?
It is not safe, their description means that they are an exchange so that's where the activity of exchange happens. It's not a place to store our Bitcoin.
Hardware wallet is a safe for long term but choose what you think is the right one for you and if you have no budget, just stay with Electrum.
