What is clear altcoin will follow the fall also its value. And for that it means we are still waiting for the resurrection of the king of Bitcoin so that altcoin is back up as well.
If Bitcoin falls to $5000, then alts will be very bad, many will not withstand and disappear from the market, because the prices of alts will be very, very low.
I think it will not happen because 2020 is expected to be the most robust year of the crypto market and investment demand is on the rise in the first few days of this year. I hope Bitcoin value could soon return to $10,000 this year and will continue this uptrend until a new high price is reached. Of course, that won't happen now and investors need to be more patient.
However, with what is happening and recently World War 3 of the US and Iran are causing a lot of investors to turn to crypto investments.
