#bitcoin $BTC Sudden disturbances always happen to some people and cause great damage, especially in futures contracts. Therefore, it is better to trade by owning the currency, especially in Bitcoin, because it has a rise that is very high and profitable most of the time, and if it falls, you can close the wallet and wait for it to rise again. As for futures contracts, they are speculation on the price and not ownership of the currency. The rate of liquidation of your funds is very fast in light of the vast rise or decline in Bitcoin. Therefore, the currency must be subject to study and monitoring before taking risks. Therefore, I advise every beginner to immediately trade in Bitcoin and buy at a time of decline. And do not be worried about your possession of Bitcoin, if it collapses, it will rise quickly, just keep calm.
