A FlashCoin is an altcoin that bypasses all traditional modes of launching. They do not make a pre-announcement. Instead, they make a thread indicating that launching is just about to start or has already begun. This causes a delay for solo miners and pool operators. This means most of the early block rewards go to a few insiders who are close to the Dev.
Another sign of a FlashCoin is they generally provider their own ‘Official Block Explorer‘ or make no effort to get one close to launch. This means it’s generally a long time until someone discovers any tricks with instamines and premines. Check our initial post on FlashCoins here.
