Analysts (swing traders, day traders) technically analyze cryptocurrency rates. Based on the probability of the occurrence of increases or decreases, they present the valuation of Bitcoin (BTC USD) in a short period of time. Day traders usually close their position within one day. Swing trading within a few or a dozen days, rarely longer.
If the result of the analysis assumes with high probability that the price of Bitcoin will fall, then we play a short position for a decline, i.e. "sell"
If, however, the analysis shows that the price of Bitcoin may increase, we open a long position for increases, i.e. "buy".
Bitcoin trading takes place on cryptocurrency exchanges. Trading with leverage (with the so-called leverage) is the selection of time options, e.g. perceptual.
Thanks to trading with leverage, the amount of investment in Bitcoin can be increased x10, x20 or even more.
It should be borne in mind that playing on Bitcoin may lead to the account being zero, so you should responsibly assume the level of risk and profit. Therefore, the safest option is swing trading, i.e. medium-term investing.
