So-called “hot wallets” make accessing your crypto easy – allowing you to transfer funds and complete trades quickly and with ease. Many providers now offer mobile apps so this can be done on the move. Meanwhile, “cold wallets” are stored offline – commonly on USB sticks – with some people even writing down their private keys on paper. The latter can work well if you’re looking to save crypto for a rainy day.
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.
