I think the "blue chip" coins will do the best with Bitcoin re-testing around the $5750 and $5900 levels, mainly those in the top 20. Specifically Ripple, Stellar, Monero, Zcash, Binance, 0x BAT and potentially Ethereum. I doubt bcash. But I also think it will be long lived and BTC will get rejected before $6k. It's worth remebering that while the cyrpto market has reached new market cap lows, the altcoins market hasn't, and instead has potentially double bottomed, at least temporarily.
In the same way the price crashed through the 6k supportl and much further, due to triggering many stop losses (as well as a massive dump), people will be selling their positions back on the rebound to this newly found resistance level (who wished they had set a stop loss originally like many appeared to of done). Simply because while a strong rebound is possible, this would be the short-term daily outcome, as opposed to the weekly/monthly outlook that looks incredibly bearish now unfortunately.
If you believe in the long-term blockchain & crypto future of finance & technology, then you still have nothing to worry about in my opinion.
