In my opinion, hardware wallets are a form of offline storage. A hardware wallet is a cryptocurrency wallet that stores the user's private key on a secure hardware device used to authorize transactions on the blockchain network. Hardware wallets are used to store private keys, making it difficult for hackers to access the keys from an online location. Also it is like any other software or wallet that you use for your day to day transactions. Extremely safe it's just a matter of securing your private key. It is the safest way to trade digital assets to keep custody of tokens at all times.

Hardware wallets are the most secure wallets because money is kept safe in these wallets. If more secure wallets are considered outside of hardware wallets, the names of several wallets such as Electrum Wallet, Mycelium Wallet, MyEthereum Wallet will come first. 

If using hardware wallet is not possible then you can use all these desktop wallets or mobile wallets as these wallets are more secure than other crypto wallets. If you keep your btc in these wallets your btc will be safe in this wallet compared to other wallets. 

No matter how much money we deposit or how much money we earn if our wallet is not secure then our income or deposit is worthless so it is very important to choose a good quality wallet.

It is the responsibility of the wallet owner, if they store the seed phrase well or with recovery phrase safely, so the hardware is the solution is not vulnerable from hacker attacks, while for Electrum there are still many cases where they lose their bitcoins as in the forum some cases before.

MyEthereum wallet is for Ethereum not for bitcoin.

It will not be safe if used incorrectly. Safe when used properly and correctly.
Software wallets can be safe if used correctly starting from the installation process, logging in, using a strong password to storing seed phrases and private keys to ensure that the place is completely inaccessible to anyone.

You are wrong. MyEthereum or MyEtherWallet? it is an Ethereum wallet which is a type of web wallet. MEW Wallet is vulnerable to phishing. How can you say you will prioritize the wallet to store Bitcoins.
This is the MyEtherWallet review link that can be studied.

Closed source wallets are terrible because they can change many things, hide many things which they don't announce in their wallet change logs and their users won't be able to detect those changes.

Hot wallets have more risk to be compromised so if he uses a hot wallet, he should store very little bitcoin in that hot wallet and he should afford to lose it. If he seriously wants to secure his hot wallets better, he can use a multisig wallets with Electrum.

I only use that computer for the sole purpose of storing my bitcoins, not for anything else, and it stays offline most of the time.

Nothing is perfect and as long as we always have a backup plan, there is nothing to worry about. I've also taken into account the lifespan of tech gadgets, and I wouldn't be stupid enough to save the entire seed phrase to the computer. For email passwords, seed phrases, bank logins, most important data, I write them all down in a notebook and keep them in a safe place. It can be said that it takes me a long time every time I need to log in or access any account, but I feel safe with it.

the thread is about Top bitcoin wallets and not mining companies, no one is talking about mining companies here. looking at your post and your post history, it looks like you are spamming ecos cloud mining which I am pretty sure will most likely turn out as a scam. aside from spamming a most likely scam site, you are also spamming a referral code which is against the forum rules.

Electrum is not a multi-sig BTC wallet, but you can create a multi-sig wallet on Electrum, just the same way you can create a standard single-sig wallet or a wallet with 2FA on Electrum.
BTC tx fees has nothing to do with Electrum wallet, the wallet doesn't fix the fee that you pay. The size of your transaction and the congestion of the network is what determines how many sats you are going to pay in fees. What Electrum wallet allows you to do is to customize the fee on desktop, and on mobile you can use the fee slider to choose your fee rate, but you have to check the mempool first to know the fee rate that is best for your transaction to be confirmed.

Do you mean hot or wallets that are at the top? Maybe this site: https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html can help you for that matter. But, if you mean wallet brands, you can refer to this site:  https://money.com/best-crypto-wallets/

Credits to the owners of those links and also to Google for finding them.

As of now, I'm only using Trustwallet. I know there are better wallets than it, but I find this one interesting. I like its simple interface and the wallet is also easy to use. It was non-costudial although some says its semi centralized but it's fine since I'm only storing a few cryptos on here and I don't really HODL a crypto for a long time. Before it, I have tried different wallets, including Myetherwallet, Blockchain.com, Coinomi, Electrum, Coinbase and the recent one is Metamask. It was a nice experience though. You can also check all or some of them and see if you develop any likings.
