Hi

what kind of daily dollar moves or increase in price action does a coin need to be profitable for day trading? Should I look for coins moving cents a day or dollars a day?? Well I'm guessing the higher the amount the price moves daily the better the trade? And I'm guessing you want sharp long spikes in increase price action instead of slow gradual increases? Sorry for the dumb question I just need clarity.
The answer depends on the amount of the investment. If you want to invest small amounts, let us take for example less than a thousand dollars. Investing in currencies with huge market capacities may not be profitable for daily trading because it is rare for prices to move by 50%, but it is easy for some currencies with small market capacities .
Daily trading is dangerous and you need to have a broader knowledge of the market to profit from it.
