Well it depends on the number of gems i can find, I'll personally say five, but the number may be low or higher, you know a lot of factors will come into consideration regarding this, however i have done a little bit of research for myself and I'll give you my top two picks for now and reason behind them, its left to you to do your research
My topmost token is VEIL
why veil?, Veil is a 100% privacy token which has taken the technology behind two privacy token giants (monero and zcoin) and combined them together to make a fully scalable, private and secure blockchain, so secure that there are no transaction history after each transaction has been made
Fun fact - the founder of pivx (a fork of dash coin) is also a co-founder of veil
And the second token is
Sentivate (DYOR)
