Well pros for wallet like Electrum is mainly security. When you use Electrum and hardware wallets, you have access to all your private keys, your seed and thus your Bitcoin. Online wallets like coinbase, coinjar...etc, have access to your keys and your Bitcoin is literally part of their entire Bitcoin fund. It is like a bank for Bitcoin. The same with exchanges. They are prone to hacking - check out the Bitfinex hack - and can easily freeze and steal your funds.

But of course, exchanges are better when it comes to convenience. But you are sacrificing security for convenience. If you are keeping/storing money, use a trusted hardware or offline wallet like Ledger Nano or electrum. You are much safer that way.

If I'm away from my computer, how do I access my Electrum? it's linked only to my desktop right?

and depending on how the owner keeps his account like ignoring his email which is likely to be phishing or any other suspicious matter. for huge bitcoin is not recommended for online wallet or wallet in exchanger.

Just like in investing, the best advice is never put all of your baskets in one egg...errr...should it be the other way around? Okay, I know you get what I mean. All things online no matter how established or fortified as they claim to be are all carrying risks. It is better to put your online wealth in different wallets though yes it can really be inconvenient at times.

These days the only secured are sites and wallets which can not be accessed online. As long as it is online, then the chance for it to be hacked is always there. When there is money inside, you can be sure that dark elements can smell them from afar. Inconvenience is nothing compared to losing some of your money. But then it is your call...nothing is guaranteed in this world that even if you diversify your wallets you can not be a victim anymore.

Just save it on your offline wallets because in that way it is much safer than you store it on a online wallet not much if you are a trader and you will be opening it every time you want to trade something. If you store in on an online wallets there are many risk you will encountered just like it will be access by the owner of that site, or else if the site get lost or become a scammed site you wouldn't get it back.

You can trust exchange websites that won't steal your funds, because only through you and me they gain profit as well the good reputation gets them more business. At the same there are several cases were the exchange goes out of use or other bankruptcy happens. It's good to hold your funds in offline wallets and hold in exchange the fund that you wish to do trading.

So far i am just usinh online wallet since I do not know how to use offline but I really want to use it since I guess it is more safer than having it on online as some stated and I believe to them too since there are lots of cons if we are using online. But for me I can easily access bitcoin in online wallet anywhere and anytime I want and even when I am.just using my phone so as long as I am connected in internet I can access to my money easily especially a local online wallet which is use only in your country

I keep the bitcoin in my wallet and I feel it is quite safe, I will keep it until I feel no longer safe or the bitcoin price increases, I will sell all the bitscoin I have.

If I were you, I would invest in a hardware wallet to give you accessibility to store coins and to have it accessible when you want to trade it on an exchange. I will never store large quantities of bitcoins on any exchange. You can watch the markets and when you are ready to trade, you can then quickly transfer coins onto the exchange. < this is not ideal, because you might miss some good trades, if the confirmation takes a bit long, but it is the safest option >

Bitcoin exchanges are prime targets for hackers, because their software sucks. ^grrrrrrr^
