To be honest the distribution of Groestlcoin is one of the best. Check on
https://chainz.cryptoid.info/grs/#!rich the all wallets (at the pie chart). I believe we are in the top10 of all wallets.
For example check Magi:
https://chainz.cryptoid.info/xmg/#!rich There are only 3574 wallets, grs has 11836 wallets. Ofcourse all wallets doesn't say anything if a coin is good or bad, but it does say something about the interest of the coin.
When the interest and/or the price would be better you could hire other devs, like Magi Joe.
