1. I got a few dollars on a paypal account that I would really like to use for trading.
If your balance is not over $200, forget using that amount for trading. You need large amounts of high frequency trades to earn anything worth while. Secondly, you would want to convert your PayPal balance to bitcoin. Bad news is no bitcoin seller likes to receive PayPal because of chargebacks. Those who accepts PayPal charge 10%-20% above market rate.
I know what to invest in! Then I'd like to hear you guys out.
If you don't know much about cryptos, stick with bitcoin. If you don't much about what drives the fluctuations in prices, buy bitcoin and hold. Trading is not really a game newbies should play.
