Yes, if you are a full time traders or day traders that you have already mastered the art of trading in which you could earn more than that 10% but not all the times you will have the luck to earn it that much specially at this moment in which the market is always fluctuating.
I agree, you can earn 10% or more daily. As long as you are studying the movement and learning your technical and fundamentals its very possible. But you can lose too more than 10% if you are not fast enough in making decisions. Trading cryptocurrencies is very risky, but it can be profitable too. Just be aware always and dont forgot to cut loss if you know where it is heading.
