At present, Monero is at the level of $172. With Monero's current ongoing stats, according to me the price can cross $500 by the end of the year 2018. Monero is the best privacy coin currently as it uses ring signature in its transactions. Transactions can only be made by sharing of wallet address which makes them completely anonymous and hence keeps the information of the sender and reciever private. Due to its codebase being so strong, the coin has been accepted by several major companies, therefore increasing its market capital.
Monero is not the best privacy coin around, as Deep Onion is. The level of intagration of ONION far surpasses that of Monero and there are new services (DeepSend, DeepVault...) which give the coin a robust feel. Wallet is perfect also, and being updated constantly - DEEP ONION is really the best privacy coin around.
