Well, you can still buy them from the hive-engine exchange by clicking here but you'll see that they are massively overpriced based on the simple fact that nobody wants to sell them.

I disagree with this.

The token prices are not overprices, the market is obviously pricing in growth. With a 26% annual growth rate without factoring in any speculation or asset growth is very good.

Plus, there are other opportunities that arise as time passes. Hopefully SMTs will open up a lot of avenues for SPI.
