Only thing necessary is for the Crypto market to mature.
CENT never disappeared, it just went offline after a rocky start.
Just be happy you managed to buy them dirt cheap while they were on the XPM/XRP/DOGE markets.
When the time is right, CENT will pop up again and continue with its main purpose.
Working on some stuff..
Will release more info in due time.
Cool ... I'll help all I can. I just envision a time where CENT paired with every other CRYPTO and CENT have its own App wallets.
"How powerful would be this coin if every reward point system in the world converted to Crypto via CENT as the medium of exchange..... and this just one of the idea that we could work using CENT!
