What is Junkcoin?

The new feature of this coin is that it added random coin size per block (see below), so even late in the game, you may still hit a block of 1000 coins! Like real gold mining, you may hit different block grade:-)

The first 100 blocks are special blocks of 10000 coins each. They are premined for bounty purpose. The 1 million coins premined will be reserved as bounties for pools, exchanges, wikis, support groups, giveaways, faucets, etc, etc. If there are sufficient interests, we can form a committee to manage the fund, in which case I will hand over the 1 million reserved bounty (minus those spent – see below) to the committee.

Release date: May 4th, 2013
