Agree with NirvanaModa. Trading cryptocurrency is possible for everyone. Another thing is someone starts quickly to catch up, while the others go down that road repeatedly but in the end manage to make profits. Besides, I think that partially success depends on chosen exchange. If, for example, you're a newbie then it's better to stick to big and reliable exchanges, like CEX. But this place is ok for advanced traders too. In addition, it's preferable for exchange to support card payments, 'cause it's simple way to buy crypto. Luckily, aforementioned exchange provides its users with such service. There you can purchase both btc and altcoins like zec with usd or eur (https://cex.io/zec-eur).
