If BTC fall down to 19,000$ again how much do you think that those top altcoins will cost? Solana, Avalanche, Terra and others, lately are you looking at the BTC chart? It looks like BTC will go Bear phase from now on, isn't it better to buy altcoins then than right now?... I'm hoping this opportunity comes though what about you?
The crypto market is already different from previous years, now the market has grown stronger as it has been widely adopted by the society so even though this year the market will enter a bear market it is very likely that the bitcoin price will not drop lower below $20k as you mentioned because during the beginning of the year to date the lowest price for bitcoin is $30k.
It won't be easy fo bitcoin to reach 20,000$. There is a lot of demand at 30K and i don't think bitcoin should go below this value. The fall of bitcoin causes altcoins to dump a lot and also if bitcoin does not recover quickly, altcoins can even go below thier tested support and many take months to recover. We have seen that many altcoins made thier all time high last year and they are 60-80% down right now.
Altcoin market is very volatile and even if altcoins are avaiable at low prices, one should always keep money management in place. Opening big position in altcoins can be risky at times.
