If you want to do daily trade at first you should keep in mind that daily trade is too risky so if you are able to carry losses then you do it. But you must have proper knowledge about market and always try to be up-to-dated.
You may trade on idex and binance those are too much reliable for daily trading because in volumes are too much than others.
Yes that is fact that day trading is too much risky but I think that we also have to keep it in our mind that day trading is the shortest way of making money, and specially in current time when there is too much fluctuation in bitcoin price and so many other altcoin prices.
