Holding Bitcoin is wise 99% of the time during a bull + bear cycle.
The altcoin/BTC exchange rate only experiences a dead cat bounce 1% of the time, and then continues on an indefinite path to zero.
For example: ETH/BTC, DOGE/BTC, LTC/BTC, XRP/BTC. The current XRP/BTC exchange rate is still relatively high, so it can be fully sold for Bitcoin.
