PayPal is not a trading platform for Bitcoin. He only facilitates us to make it easier to buy Bitcoin using a PayPal balance or credit card.
If we have already bought it we are not advised to hold it there, better withdraw it directly to a personal wallet.
I agree with you, because if our bitcoins are left for too long, it will trigger an event where the account will be locked. I still don't really understand why there is some kind of account lockdown, if the reason is due to too much activity, in my opinion it's only natural. because in general, paypal is only limited to making it easier for us to buy bitcoin with a paypal balance.
so if the purchasing activity exceeds the maximum, then paypal will automatically detect transactions that are not fair.
For example, in one day paypal makes purchasing rules a maximum of 10x a day. if it exceeds 10x, paypal will lock and check the account. and reopen it when it is free from suspicious activity.
