6. Monero (XMR)

Would you like to find out more about Monero? That’s another coin and those who invented it focused on security and privacy. It is different from Bitcoin in its approach. As we know, transactions performed via Bitcoin are all public, while Monero’s transactions are not fully visible and part of them is hidden. If you need more privacy, consider Monero. You can finally have what you have longed for. There is an opinion that Monero might be used by criminals who want to stay invisible, but dishonesty existed before Monero was created so you will feel no negative effect. After all, people who have no criminal record and are not willing to do anything illegal may also hate to be observed by a third party. The five coins we have previously mentioned may become popular, but there is no 100% guarantee.

5. Ethereum (ETH)

Do you know that most experts think that Ethereum will be the main digital currency? This coin can be used as a platform creating ‘smart contracts’. This feature allows you to make a framework for other users to create new currencies and coins in addition to this one. If any of the leading brands like Microsoft decide to establish a digital coin to reward people who wish to use their coin, then it is very likely that their coin will be based off Ethereum. We can compare this currency to the Internet. Ethereum helps to create new currencies, which makes the currency highly valuable.

4. Lite Coin (LTC)

Now let’s see what’s so special about Lite Coin. This currency was created based on a totally different sort of approach. Its algorithm is different from that used for Bitcoin or any other coins mentioned above. This currency has been around for quite long. It was established in 2011. The language of this currency is also different from the rest of the coins. It is hoped that in the nearest future Lite Coin will keep gaining popularity among customers.
