Bitcoin is the only way I can invest to some crowdfunding that is why its the only I use. Besides my paypal was already frozen months ago, I don't think they I can take it back either.
Paypal really causes a headache for investors like you. They were not like that before but they started to become more strict and i guess trying to follow their own rules which is actually a good thing for bitcoin users because this certain paypal users will migrate to bitcoin and would become an opportunity for some webmasters.
