SPI  purchased with the Curation Rewards of NeoxAG. 
NeoxAG is automatically a 50/50 split,  so we take the 
50% liquid NEOXAG and buy SPI.  The other 50% stays 
"powered up" and we will discuss power downs at a later date. 
I'm giving it at least 6 months, the account is growing well and 
we have about 20k NeoxAG "powered up"  less some gifted 
stake that the account got very early on. (~3,008)  
That will stay in.   
In short.  all payouts are  SPI.  Which is liquid steem power, 
and is growing very rapidly as compared to Steem Prices. 
We gained over 20% in the first 6 months and voted on a 
Token "split" which meant that  all our SPI tokens had 25% 
more added, which revalued the tokens back to 1 steem each. 
But I went from 10,000  to like 12,500 in the process👍💪
I am a big SPI HODLer   and it has hedged my Steem price 
rather well! While Steem Prives have dropped form 16 to 12,  
I am nearly EVEN  over this bear market.
