I think you can invest in Specter. This is a very good project, Specter is selling ICO and the success rate of the project is very large when it has a very professional management team and community supporters. I have invested some money into it. You can study to invest in spectre.
+1 for XSPEC
The other coins are great but $300 for Zcash/Monero looks a bit toppy to me.
I would vote deeponion but I have concerns about what happens when the air-drops run out and the 'paid-for' schills stop posting as much.
