PayPal is bullshit, it's not an investment, just a payment processor. I mean there 1$ remains 1$, no increase and no depreciation.
But in bitcoin, it's like investment, the value of your investment increases or decrease following the market trend.
If your $1 remains $1 while receiving through the Paypal then I would say you are very fortunate. I live in a country where there are critical restrictions on the usage of Paypal. We can only accept payments with Paypal and that too by paying some fees and then the funds are automatically withdrawn in to the bank account associated with our Paypal account due to the regulations of the government.
