Short BTC & ETH Here, Thank Me LaterCoinMarketCap 20 Index DTFCRYPTO:CMC20USDJordanBelfort4Large-cap cryptocurrencies (BTC & ETH)should be considered reasonable targets for short-selling today. CMC20USD is an ETF tracking the combined market capitalization of the top 20 cryptocurrencies; it has now reached a critical resistance level within a descending channel, a trendline where major cryptocurrencies face intense selling pressure. Lets see. A 3-day candle closing above the red price on the price tag would invalidate my analysis.
