Though I can't understand your statement clearly but will reply: Coinbase is a digital exchange where you can trade cryptocurrency for fiats or fiats to cryptocurrency, for those who know how to trade their coins will make their profits from the said cryptocurrency exchange but some will still loose their funds too. If you can trade, then you're good to go for profit on coinbase. On this forum you can't make profit  but the advantage of this forum to coinbase can't be overemphasize. Coinbase is well secure and good for traders.
