Do you think I would need a business paypal account to conduct this or would a personal be ok? Again, the person im dealing with is completely trusted, the problem im facing is taxes and would paypal shut me down.
Having a Business account is way better for receiving large sums.However,the risk of Paypal locking your account remains.You will have to lie about the origin of the incoming transaction.Never mention to Paypal that you are selling cryptocurrencies for fiat money.They will most likely ban your account.Claim that this payment is for web design services,or some other expensive digital service and you'll be fine.
If you can verify your Paypal account with real info about yourself,everything is going to be alright.
I used to sell BTC for Paypal funds 3 years ado on Localbitcoins,but I stopped doing this,because the Paypal fees were getting worse and Paypal limited my account twice.I managed to lift the limitations,but I thought that it's not worth it to use Paypal for such activities.
