Decred is too high to buy now. It was a good buy when its price was less than 100k satoshi.
At this price not a good buy at all, I would rather buy other undervalued coins. All the anon coins are up because of DASH and XMR.
I am still looking at SDC. It is a good buy below 200k satoshi.
You say Decred is to expensive but looking at SDC? The actual "pump" is SDCs last breath. The devs abandoned the coin. You have to convert it into "the new coin" from the developers. The press all across twitter, reddit and even here on Bitcointalk is bad about this.
If you want to take a look at a undervalued coin why not give POT or DGB a try?
