I have been in the cryptocurrency circle for 16 years, doing projects, mining, and speculating in cryptocurrencies. I have changed from an investor to a speculator. I have no faith anymore. I have lost my faith in BTC, so I can’t play the annual line. I have switched to daily speculation. I also often speculate in ultra-short contracts within 60 minutes. But I know that I can’t short BTC, I can only short the altcoins. I can’t short Ethereum at a high multiple, nor can I short the altcoins at a low level. I can’t short Ethereum with a small volume, otherwise the market will be forced to close without a counterparty. Holding a short position is also a transaction. There are only losers and winners in the cryptocurrency circle. If you clear your position, you will be the winner. As for the grasp of buying and selling points, there are too many systems that you need to learn by yourself to not be a waste. The transformation process is very painful. All your trading preferences must change. You only look at winning and losing, not talking about faith. I can empathize.
