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.
I also give my vote to that coin, monero and dash are great but the price has gone up even more so it is really difficult to justify paying so much for such coins when other got them at very cheap prices, and while deeponion seems like a decent project most of the coins were distributed and that is a problem since most people are going to sell them immediately and that is going to crash the price.
