You made a good decision mate by investing at this dip because for most active traders also follow the same strategy.All these FUD and FOMO are spread to buy at the dips by whales and most of weak hands sold to large investors.The main thing is investment in Bitcoin and just hold it for long term and enjoy your gains in the long run.So your $500 investment or say 0.012 Bitcoins at $43k would give high yielding returns in future if you are patient and follow same strategy to invest at dips.Best wishes to you.
