I like the idea of Monero XMR with its privacy features. It is a well established coin with long history and by having its transactions untraceable unlike bitcoin found its target audience. Its price is very stable and currently in constant uptrend, and what is more it is in constant developement.
Well, Monero is good privacy coin and can not be tracked.
I think many investors used this coin for their transaction.
But I personally didn't like to invest in this coin, just used for transaction.
I think invest in top 10 coins are more safe .
