If bitcoin surpasses the $60K level then it will hit higher than $100K

If bitcoin surpasses the $60K level than it will hit higher than $100K. For altcoins I won't suggest you to hold the tokens/coins having marketcaps in billions except top 5. It is also possible that big altcoins like ethereum may drop to 0.016 BTC if Bitcoin jumped to $100K. But I am not afraid regarding Litecoin because Litecoin is next to bitcoin. Litecoin will hit higher than 0.005 btc and possible to make its resistance at 0.01 BTC. For other altcoins like ADA, Algorand etc I won't suggest to hold as in Btc these altcoins will be dropped to half (around 50% decrease is possible) even ADA has the upcoming update in FEB. But I suggest you to hold altcoins having marketcaps lower than 50 million like ARK and it is possible for ARK to having greater marketcaps than 50 billion in the future. FOR Miota and EOS the bitcoin dominance won't affect because both altcoins have faced a long term btc dominance so the bear market will prefer to hold these alts rather than to sell them.

We might see some investors from the end of 2020 deciding to cash out as the first quarter of 2021 draws to a close.  It could just be a dip in the markets as has happened this last week when BTC went below $50,000 for a few days, or, it could drive the price down $15,000 (or more) if investors are rattled by the sell-off.
