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.
Why they are frozing accounts? Because bitcoin deposits?
That's the problem with centralized payment methods, they make the rules, you just obey.
Nope, They consider a lot of instances to freeze your account. If they feel so that you currently disobey they TOS then your account are surely going to be frozen. Some of the paypal user's as well thinks that they are just doing it without any reasons.
