One of the old coins that I hodl is Minexcoin (MNX), I know the developer is no longer active, but if I sell cheap now then what for, I'd better keep it until it becomes trash.
I dont trust minex team, they look like most project that are only waiting to bull market to pump and have scam exit. we need to be smart with our position in this market. I sold my minex at almost the ATH price and Dont think I can hold the coin, considering the community, team in-activities and market cap. We need to be sincere with ourself some coin are meant to be sold out completely especially with there present position in the market.
