I have little money of about 100$, Is it a good idea to start jump on Bittrex or Poloniex and
start buying alt coins for profit.
For daily income, I don't think so, but for weekly, or monthly or yearly income I think I can. But if you choose weekly or monthly, the benefits you can get are not so much. It all depends on the conditions of the currency at the market place, even if it is uncertain every week or month the currency will increase continuously. Because passive income can only be done on long-term income.
You have to trade for a daily income, which is known to be more risky trading, as opposed to holding a currency that has already been bought and then sold when the price goes up. In trading, we both sell, but we need to pay attention and predict the ups and downs of the currency being traded. Do not let us make mistakes in predicting and selling it when we put a big price. If you are an expert in trading it is not difficult to find daily income from trading.
