BTC weekly chart shows long wicks, and overbought RSI. Historically since 2014, BTC retraced to almost half of its value when that happen.
I think a retest of 6K is not out of the realm of possibilities at this time.
The upcoming weeks might be really ugly for BTC. Im not sure what that will do to the ALTS, but it probably wont be nice either.
Sorry for this doom and gloom prediction
