Monero. No one can see how many coins you have or where you get them or what you will spend them, as everyone can see in most of coins. Transaction fees are less then cent and dont seems to grow anytime soon. Coin have strong community and after Etherum and Bitcoin best development. It was a fair launched coin that had no ICO or premine or instamine, so will never have any problems with SEC.  And when you look at it right now when all coins crash, Monero is gaining toward all including Bitcoin.
