Can any one help and tell me what is going when you can buy rise or fall on BTC and where i can do this? You can set a time limit as well.
Thanks in anticipation of your help.
If the price drops you can use a short sale for Bitcoin. Short-term selling means a trader buys a contract which makes a profit if the future price is lower than the price at which the contract was purchased. When the market is trending downwards, or when entering a bear phase, you can do this technique to make a profit or to protect their assets from weakening prices.
The futures market (long term) does carry a very high risk. So, technical analysis is needed and appropriate to project where the price will move. For a professional trader, the futures market is commonplace, because a large risk is directly proportional to the amount that will be obtained. In fact, this technique is suitable for use with Bitcoin, considering that BTC is at the top of the exchange and its price can quickly return to normal. I think long-term selling or investing is suitable if you use this currency. But if you are good at it and can do it for the short term, I don't think it will be a problem either. Do not use big money if you do short-term trading, it will be very risky, if your analysis and predictions are wrong.
