convert it to paypal (1:1 rate) when the price is UP
too complicated and difficult to do that, you need the services and fees high enough for it.
No need to convert BTC in paypal. We are using bitcoins because we want to say good bye to expensive services like paypal or western union. If you want to invest bitcoins, try to gain profit from trading, as trading with altcoin is the only legal method to earn the profits.
