After what XRP was listed on coinbase it was obvious that in near future XLM will be among added coins. It is big deal though we are not seeing significant immediate results. Impact of being on coinbase will be seen and felt across the market in next bull run. It is big day for Stellar believers today and must be celebrated.
Considering how much stellar has fallen in price now, and is one of the most undervalued coins, the project will easily be able to regain its position with a favorable news background.
