The Coinbase smartphone app, however, offers a diverse feature set beyond what the Coinbase website delivers. Using the Coinbase app, which is available for both iOS and Android devices, it’s possible to purchase and store Bitcoin via in-app purchase functionality. In addition to Bitcoin, the Coinbase app also offers investors the ability to purchase either Etherium or Litecoin, the two most popular altcoins on the market.
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.
