Anonymity is indeed a very expensive thing. Monero has proven that. Dash has proven that. Even Verge has proven that, even though its about as anonymous as Oprah Winfrey. This is why the time is now to get on board with Spectrecoin (Xspec).
It is very inexpensive compared to other coins already mentioned, and it has already proven tech. Couple that with default stealth addresses and stealth staking to come in Q2 of this year, and you've got a speculative winner.
Or don't buy it and miss out. Your choice.
