Having 25$ as an investment was a good start for me, especially in investing on trading it will be a good start. But I cannot say how much would it be the profit in one, the answer is in your hand if you think you are good enough knowledge in trading you can make it more than that amount.
Yes your results will depend on the knowledge that you hold about the trading and what coin you choose for making an investment and if you choose a right coin at a right time and if price pumps then it can give you better profits beyond your expectations.
