Let's think about this a little.  Jy-p is bankrolling this project with Comany 0 to the tune of 60-70k a month.  Do you really thing he's putting in so much time/effort/money for 8 lousy btc?  With the initial airdrop, they gave away what amounted to hundreds of btc.  With crypto projects its key to have appropriate expectations.  If you were expecting mass gains overnight and are upset that didn't happen, you may be leveraging more than you should.  Assuming you will not miss 8 btc over the next year, I submit that you will be happy with your return as the devs continue to toil away.

But lets look at where you stand currently.  So you spent 8 btc on decred.  Great! Did you know you can grow the value of that much more than any bank account can give you? I suggest you look into staking with one of the many stake pools available.  I've been very happy with my "interest" earned regardless of the price of decred.  So check out the pools available to you listed at the bottom of dcrstats.com and give it a try!
