Coinbase is working hard to get back it's reputation and again develop its trust with users.
Recently bitcoin cash damaged the reputation of Coinbase with the biggest dip in its price graph. The main reason behind this dip is insider trading of bitcoin cash but apparently everyone believe this dip is due to coinbase listing of bitcoincash.
i believe if ETC and RIPPLE will behave same like bitcoin cash the coinbase will lose all of its reputation.
