One of my friend say, the panic of non believer is our way to make more profits. Thats mean our chance to buy more cause the price is dropping and wait a little but until gain profit from it. But dont be so naive though, if its time to cut some lose just do it.
Your friend correctly tells everything. People who do not trust in cryptocurrency or trust not so Kam we, at mass panic they sell. Thereby give us the chance to buy at lower cost of a coin.
