Liquidity is important. That's the way to attract many trader/investor invest in that coin/token
But ofc, it needs reason to get good liquidity, such as good project, good team, partnership, community etc.
Those are what should coin has. If not, liquidity wont be reached. Or even investor wont see the coin
Liquidity is always considered first when investors look at the project because if that coin can not make investors feel secure, it is just shitcoin and you should find ways to stay away. In fact, exchanges like Latoken, p2pb2b or Hotbit have very poor liquidity and many of the projects listed here make people feel uninterested in participating.
I think currently should only choose to invest in large exchanges such as Binance, Okex, Huobi because this is the top 3 largest exchanges in this market and the liquidity is always very high so there is no need to worry about trading.
