And the first bi-month re-balancing of the Top 30 has been completed:
BitConnect (BCC), Golem (GNT), MaidSafeCoin (MAID), TenX (PAY), Basic Attention Token (BAT) exit the Top 30 because they don't meet the selection criteria (anymore).

Very promising coins for 2018 enter the Top 30: NXT (NXT), Ardor (ARDR), MonaCoin (MONA), Populous (PPT), Cardano (ADA).

And as of today CombiCOin is a whopping 383% up since Nov the 7th!
