I have never done it before because PayPal is not accepted here in my location. Investment in cryptocurrency using PayPal is of no difference from the use of exchanges though.
you have a US-based account and if your account is verified, buying bitcoins with your balance or credit takes just a few seconds. Earlier in the day, I bought bitcoins worth $55 when the price was $33 and now the price is $37 and I have profited about $3 just by holding bitcoins.
