If you buy and keep bitcoin on an exchange, you trust them to keep your bitcoin safe and let you withdraw anytime you want to withdraw
But what happens when they shutdown?
It is much better to buy Bitcoin and keep it under your control, because it is not advisable to keep it under the control of a third party. Whenever the exchange authorities see a little more Bitcoin in your wallet, they can stop the transactions in your account, then all your Bitcoin will be trapped.
For example, a few months ago, the KuCoin exchange did such activities, closing many accounts.
You might have problem getting your bitcoin back depending on what's happening with the exchange
It also made me wonder if it is the current market condition that's making some of the exchanges struggle. When people are not really trading, making enough money to keep the business running can be hard
Am not saying it's the market condition that's making the exchanges shutdown, there could be other reasons too but for people that want to hold bitcoin for a long time it raises an important question
Anyone who plans to hold Bitcoin for a long time should definitely not use an exchange, because storing Bitcoin in a strong wallet is a much better and better plan. I see many people lazily buying Bitcoin from an exchange and depositing it in an exchange, they are basically making the biggest mistake, your Bitcoin is not under the control of others at all.
So if you can, you can use a hardware wallet, and among the many software ones, you can use Electrum wallet.
If an exchange can disappear anytime, where should we really consider keeping our coin?
Should we leave exchange completely and switch to a non custodial wallet?
You should not trust exchanges at all, that's why you must choose a permanent and reliable wallet. And you should deposit Bitcoin in that wallet so that you don't face any problems if you deposit it for a long time, so it's best to adopt a reliable wallet and you will be successful in the future.
