You can’t simply go to a bank and ask for any digital currency. Instead, you’ll need a proper digital platform for making any trade in Bitcoin, Ether, Ripple or as a matter of fact any crypto. After all, that’s the whole point of creating digital currencies. Cryptocurrency exchange platforms are such online portals that allow you to exchange a digital currency (cryptocurrency) for another one or even a fiat currency depending upon the type of exchange.
Why is it strongly recommended to invest only the amount you can afford? There is a psychological reason for that. When you use your own money that you can lose, you will not be vulnerable to different types of emotions that can ruin your deposit. Fears of losing all money that you have borrowed from the bank or friends will affect negatively your trading results.
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.
