I think verge is one of the best privacy coins available for monero. The coin provide complete privacy and its transactions are secure and untraceable. It's transactions are super fast and it takes 5 seconds on average for the transaction to confirm. Verge is very popular and it has a daily trade volume of more than 3 million. The coin has a lot of potential to grow and you can expect a price of around 0.01$ within 2-3 years or so.
