Only a few cryptocurrencies – such as Bitcoin and Ethereum – have achieved mainstream levels of popularity. However, even well-established currencies can fall victim to extreme price volatility. It can be difficult to predict how prices will fluctuate with newly minted coins because there is little historical information to analyze. Backing a new currency could prove extremely lucrative, but equally, there’s a chance you’ll make an expensive mistake if you don’t know what you’re doing.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
