10$ in altcoin would be enough for daytrading. If you can make every day little profits, you will multiply your funds. If you loose, you only loose 10$. On most exchangers the min. trade is lower than 10$. Fees are around 0.025 and 5 %.
On daytrading you have fast moves, because you don't follow the main moves, but secondary and third moves/waves. Daytrading is like gambling and no indicator will give you a chance over 50% to take profits in opposite to middle- and longterm trading. So keep your funds as low as possible for daytrading.
