Ok so after years of buying and selling BTC i just want to say this.
In my experience the safe way is via your bank account and coinbase.
When you sell via paypal you get scammed, tons of people buy with a hack/stolen paypal account.
( You will just end up with a chargeback )
This is the same with most all providers not just paypal.
What i am highly recommending is using coinbase to buy and sell even though the commission they take sucks its still 100% safe.
This is your experience and i see that you feel good about the past.
There are many other exchanges where you can buy bitcoin through banks (depends which country you are from)
