Short on $BTC

I want to short bitcoin and other cryptocurrencies. My explanation is that I believe bitcoin is overvalued and that it is currently in a resistance zone. Long-term investments are challenging because of how volatile and unpredictable the crypto markets are. I can profit from these changes in the market by betting on the price to decline by shorting bitcoin and other cryptocurrencies. It can also be used as a hedging strategy to guard my portfolio against losses in other markets.
